It’s possible that solve the hurricane problems with proper building regulations and lower the risk of huge wildfires with controlled burning. But the US as always prefers to pretend that there’s nothing to be done when other parts of the world has figured it out.
We have cyclones here similar to the hurricanes in the US and usually it just blows over some trees maybe causes a power outage. The absolute worst I have experienced was 3 days without power. I have never seen a house destroyed by a cyclone here.
As for wildfires, they do unfortunately claim a few houses most years.
Hurricanes are mostly just flood damage in the US, and some wind/debris damage exactly like the blown over trees you mention.
Houses generally aren't destroyed by hurricanes in the sense of "the storm literally ripped them up", they're made uninhabitable by storm surges (flood).
The scary ones are tornados.
And tornados do genuinely fuck shit up. Even in those "enlightened" parts of the world you think have proper building regulations. If you're interested, go look at the recaps of tornado damage where they hit Europe here: https://en.wikipedia.org/wiki/List_of_European_tornadoes_and...
Note the number of homes destroyed and people killed - plenty of both, even in those countries that prefer brick/concrete homes.
Hurricanes throw branches. Tornados throw cars.
Tornadoes are quite a bit less common outside of North America, and especially the US. Some of that comes down to the absence of people in the places where tornadoes occur, so there's no one there to report them.
The Tornado Archive (https://tornadoarchive.com/) has a pretty well executed map to illustrate that. They report that between 2011 and 2021 (just the dates I punched in, so its possible the actual ratio is a bit different from that), the world saw ~20,000 reported tornadoes. North America reported 12,000 of them.
So its not just that Americans maybe don't know how to build tornado resistant structures. Its that the US and Canada's per-capita tornado rate is quite a bit higher than the rest of the world.
Also, the list of tornadoes the GP refers to in Europe are mostly F0-F2 severity. These don't often cause high fatalities and injuries in the US either (on par with what's reported there). The problem is that tornadoes in the US Midwest and Southeast are often in the F3-F5 range, which are much deadlier. An F3 tornado includes winds to 165 mph, which is considered a category 5 in the hurricane scale. They don't last nearly as long, but high intensity tornadoes can cause catastrophic damage in seconds where they hit directly, unless the shelter is literally underground.
The quantity of energy in an F5 tornado is literally on the same scale as a nuclear weapon, albeit delivered more slowly. Given that context, their ability erase towns should not be that surprising. You can't engineer a practical structure capable of withstanding those kinds of forces.
There's also that, but I didn't go to the effort of investigating the rate of various strengths. I'll bet their data explorer shows that aspect of the phenomenon too.
I suspect that a major factor is that the great plains of North America are at a lower latitude than e.g. the Eurasian steppes, so 1) there are fewer people living there and 2) the confluence of meteorological circumstances needed to generate a lot of tornadoes (and therefore a larger population of very destructive tornadoes) just aren't present anywhere else in the world.
This whole line of reasoning "Americans must be bad at house construction, look at all the destruction wrought by hurricanes/tornadoes/etc" just feels disingenuous to me. Like observing "look at how much better the British are at building volcano/earthquake proof buildings, you never hear about people losing their houses to lave in the UK!".
> 2) the confluence of meteorological circumstances needed to generate a lot of tornadoes (and therefore a larger population of very destructive tornadoes) just aren't present anywhere else in the world.
This is in fact a huge part of our tornado risk in the US. The long north-south region of mountainous/high elevation (i.e. the rockies) going into a large low elevation flat region, helps create the 'layering' of different air temperatures that cause tornadoes once the current changes enough for the top/bottom layer to turn into a column.

The insurance companies have done research on the topic (including building giant 'labs' with a large number of fans)

and have developed standards/techniques that home builders/owners can do to fix a bunch of problems, starting with roofing:

Tornados might be more intense but only for a short period of time and in a small area. I don't see any of those where the tornado is lasting days, causing sustained damage. There are some where there are multiple tornadoes in a span, but each individual tornado is itself quick and violent but localized within a mile or so at most.
Compare some incidents with, Hurricane Sandy, for example, where it traveled across the span of a thousand miles and lasted a week of damages.
Yes.
Tornadoes seem like a phenomenon for which insurance is actually a pretty good part of the solution. I mean, it is very unlikely for anything in particular to get hit by a tornado, but it is really devastating. It might take an unreasonable amount of work to build everything to the level where it can sustain a direct hit by a tornado. The expected value of tornado damage is quite low overall, we just need to deal with the individual catastrophes that occur.
Hurricanes… I mean, there are different sized hurricanes in different areas. For the ones that hit Florida, part of the solution is probably legitimately that we should have fewer people living there, because there’s going to be a widespread devastation there occasionally. And if you live in a hurricane-prone area, you are going to get hit by one eventually. (So like what’s the bet here? The insurance company knows they’ll probably have to pay out eventually).
Just to put a number to it, 2024 was apparently an unusually busy year for tornadoes, around $6B. That isn’t nothing! But one single hurricane cost $7B in 2024… and there was a $34B one… and a $79B one… who’s insuring the southern coast of the US? Seems rough.
You can build houses which are much less likely to be seriously damaged in a hurricane. Some more ambitious designs are virtually hurricane proof. You never see high rises knocked over by a hurricane, for instance. Because they are (mostly) built correctly. Otherwise downtown areas in the entire Gulf Coast, Mid-Altantic, would simply not have existed for more than a few decades.
The same goes for floods. Most of the problem with floods, is that the house frame and flooring are made of wood. And wood rots. If you live in a flood prone area, the first floor at least, should be brick or stone for just about everything. Yes its expensive. But so is is $800/month flood insurance. Or having the federal government bail you out and passing the cost on to the taxpayer
But building things correctly is more expensive, and Americans love their cheap McMansions.
Also, on an individual level there is less incentive to build correctly, because you will almost certainly not get a discount on insurance. 99% of the population is at the whim of either buying a used house, or whatever the builder's models are for new construction. Its really only possible if you are very wealthy and build your own house on your own plot.
If you have to be inside one, pick a hurricane. But tornadoes are so much smaller. This list is like... 10-20 per year with an average of less than 1 casualty and a dozen houses damaged? That's basically zero as far as insurance and habitability go. I found a study titled "Tornadoes in Europe An Underestimated Threat" and it has an estimate of 10-50 million euros per year in total damage. That's not even 1 euro per house in Europe.
Let's not be silly here. European tornadoes are not taking apart houses to the foundations. Ripping off roofs or flipping over cars or even when trees are falling on a tourist tent and killing them in process has nothing to do with how houses are built in USA and nowadays even in UK and elsewhere.
The real problem is that we're politically/socially unwilling to transfer the risk to the people who are responsible for creating it: Wealthy coastal landowners believe that the cost of home insurance should be about $2000/year. If their properties actually cost $200,000 per year to insure, then that's what they should have to pay! If they don't like it, they should either build something cheaper (that's the other half of the product) or move to somewhere with less risk.
Tornados are almost the perfect example of an insurable hazard: Very low probability, very high damage, very widely distributed across the affected areas:
https://mrcc.purdue.edu/gismaps/cntytorn#
Click around that neat interactive map, you'll see that the tornado is typically a few miles long and a few hundred yards wide, there are a few thousand severe tornadoes scattered all over the Midwest and somewhat fewer on the east coast in the past 70 years. It's not feasible to build houses everywhere that will stand up to an F5 tornado throwing cars. But they only cause a total loss of a tiny fraction of all houses in the country, and there are relatively few choices anyone east of Texas can make that would meaningfully impact their risk.
You could price insurance premiums at the risk of a tornado times the cost of the insured assets, plus a 10% administrative fee/profit margin, and those rates would be affordable. Maybe a handful of people would choose to live in Colorado instead of a few hundred miles east in Kansas because the cost of this 'tornado insurance' was higher in Kansas, but even in Tornado Alley it wouldn't be unaffordable.
Conversely, if you look at the hurricane incidence and storm surge risk map:
https://coast.noaa.gov/hurricanes/#map=4/32/-80
https://experience.arcgis.com/experience/203f772571cb48b1b8b...
and population density along the gulf coast:
https://luminocity3d.org/WorldPopDen/#7/28.541/-88.011
It's clear that people are choosing to build houses in the narrow strip of low-lying land that's right along the coast and vulnerable to high-probability storm surges! If insurance was priced at cost of assets + administration times risk of loss, it would be really, really expensive.
> If their properties actually cost $200,000 per year to insure, then that's what they should have to pay! If they don't like it, they should either build something cheaper (that's the other half of the product) or move to somewhere with less risk.
Or build something adapted to the risk it faces. In my home town there are houses that were built on flood plains that have recently been flooding every 5 years or so. Luckily they are brick and in order to get these covered you now need to install flood barriers over the doors, and your ground floor has to be adapted to flood without sustaining damage (tile floors, special plaster etc.)
Now when we have a severe flood warning people will move their valuables upstairs if they're house floods they just have to clean out the mud. There are also a couple new houses right next to the river that float and rise and fall on stilts when the banks burst.
I think most people would go for adapting their designs, but insurance companies would have to make that offer first since they ultimately decide which designs are insurable for which amounts.
> we're politically/socially unwilling to transfer the risk to the people who are responsible for creating it
This is important. Insurance was invented 2000+ years ago but aggressively deploying technology that worsens floods, weather, and fires is only around ~100.
> The real problem is that we're politically/socially unwilling to transfer the risk to the people who are responsible for creating it
A lot of the responsibility falls upon governments who are lobbied by developers to zone areas for development that should never have been zoned for development in the first place.
I talked to somebody who owned a beach house in South Carolina about 5 years ago and if he wanted flood insurance it would cost $5,000 / month.
How much was the house worth?
It was a 50 year old house. Land probably worth more than the house itself.
The real issue is global warming causing an exponential rise in tail risk events. It's exponential because even a linear shift in temperature causes an exponential rise at the tails (look at how a normal distribution works).
Insurance is based on statistics. The math they use assumes stationary distributions. Insurance companies can't deal with shifting distributions well so they take the losses and then exit markets.
Global warming is going to mess up insurance as we know it for that reason. Not sure property insurance, but all kinds of insurance.
This is mostly a probability nitpick:
Most disasters follow power laws and other fat tail which don't have the same effects in the tail as a Gaussian. If you shift 1/x^a by c, you "only" get a polynomial increase.
But also, if you shift the mean of a Gaussian, the increase isn't exponential, it's super exponential (e^(x^2) to be specific).
> Insurance is based on statistics. The math they use assumes stationary distributions. Insurance companies can't deal with shifting distributions well so they take the losses and then exit markets.
Sure they can, that's why they hire statisticians. They routinely deal with insurance of much rarer events where we have much worse models than climate change. They're just banned from charging the actual rates, because it's politically unacceptable.
They exit markets due to regulations banning them from charging the true cost of risk. Large insurance companies don’t just go broke. They have re-insurance that caps their losses. It’s becoming far more difficult to get reinsurance and the premium caps make reinsurance unaffordable for the insurance company so they leave. The business model is managing the money - they don’t much care about the claim losses over the long term and taking 1 percent of rising premiums to be a manager is a solid business model.
Tornados are indeed scary. I have seen a house cut in half like a knife by one. You could see the doors ripped off the medicine cabinet on the second floor and meds still on the shelf.
But tornados are also significantly smaller. A hurricane will damage a thousand square miles while a hurricane will mess up 50. It’s not quite right but the proportions are in that ballpark.
the US would avoid flood damage if they just built apartment buildings. Asian apartments towers are immune to flooding because they allocate the ground floor to parking. Can't blow the roof off a square concrete building either.
Ofc, a sufficiently strong Tornado is destroying everything in its wake. But, they're rare in comparison.
>the US would avoid flood damage if they just built apartment buildings.
What do you mean by this?
You missed the next sentence.
> [...] immune to flooding because they allocate the ground floor to parking.
The 2024 hurricane season damage totaled $128.072 billion.
I couldn't find data for tornadoes in aggregate, only individual storms.
> Economically, tornadoes cause about a tenth as much damage per year, on average, as hurricanes. Hurricanes tend to cause much more overall destruction than tornadoes because of their much larger size, longer duration and their greater variety of ways to damage property. The destructive core in hurricanes can be tens of miles across, last many hours and damage structures through storm surge and rainfall-caused flooding, as well as from wind. Tornadoes, in contrast, tend to be a few hundred yards in diameter, last for minutes and primarily cause damage from their extreme winds

As the governments in the US get increasingly incompetent, insurance prices are going to have to rise. Government services are largely there to protect you during black swan events, so if those services get less and less effective, you're going to need more insurance for those events.
This was the whole issue. California made it illegal for insurance companies to raise rates, so the insurance companies stop renewals. Leaving everybody uninsured. Homeowners couldn't buy insurance at any price.
Public insurance. For housing, healthcare, maybe even cars (since the coprorate political complex insists that we HAVE to drive everywhere). At some point, we have to accept that the middlemen are siphoning value, not providing any. Vanguard it and let elected admins set the codes.
> Public insurance. For housing
This is California’s FAIR plan [1]. It’s a wealth transfer from non-homeowners to homeowners, homeowners in low-risk areas to high-risk homeowners, and from low-value homeowners to rich ones.
That was one (corrupt) option. Another would have been to draw funds by taxing homeowners, specifically, and limiting payouts by fire risk, capping at a mean replacement cost, not per-house. That that's not what happened is an issue with the implementation, not the base concept.
> draw funds by taxing homeowners, specifically, and limiting payouts by fire risk, capping at a mean replacement cost, not per-house
This almost seems designed to maximise fury. You're still taxing low-risk homeowners to pay for high-risk damages. And when a catastrophe hits, you aren't paying enough to rebuild (or avoid bankruptcy, in which case you're just routing taxpayer funds to creditors). Add to that you've branded it a tax increase it's almost something the GOP would run as a false flag against a Democrat.
Isn't this thing going to be subsidized by taxpayers in the end anyway?
California already a dumb communal insurance thing, the "California FAIR Plan" for people who can't get insurance due to high risk. They force insurance companies who operate in the state to fund it. So basically everyone has to subsidize the high-risk people... but then the insurance companies leave.
https://www.cbsnews.com/sanfrancisco/news/california-fair-pl...
As someone who's home insurer pulled out of California and so I had to scramble to find another carrier, I looked at the FAIR plan and it is completely untenable for most people. My insurance was already high, ~$2000/year for coverage that would rebuild our house, and under FAIR it would have gone up to $12000/year.
I mostly agree with the article that insurance is grounded in statistical measures of risk and there's no point railing against it. Norms are going to have to adapt to increased risk and how we build homes and infrastructure needs to shift away from short-term, low-cost thinking to longer-term solutions with a higher-upfront cost and lower TCO given the new constraints. Things like burying power lines, aggressively managing fire danger, and homes that are built to be more sound to natural disasters have to become the status quo.
Most of these things are already possible today. In my neighborhood, PG&E did an assessment and it would cost every homeowner on the street ~$25,000 to have the power lines buried. I would have opened my wallet immediately to reduce the fire risk, but it got caught up in politics and policy. When we had some renovation on our house, my wife and I insisted on some of the work being done in ways that would make the house safer and easier to maintain over the long work. The contractor balked at first saying it would cost us an extra couple of thousand dollars. I had to point out that an extra $3000 to make sure things lasted an extra 5 - 10 years and was easier to maintain and upgrade meant nothing. But people have to insist on doing better because right now the norm is to cut corners on everything to save in many cases a negligible amount of money over the life of the work or against the cost if there is a disaster.
The building codes will need to reflect the new normal. Defensible perimeters, metal roofs and masonry or cementitious exteriors are a must for many areas going forward. Log cabins amongst the pines just aren't tenable in the West any more.
You say that... but a well built log cabin, with a Class A fire resistant roof, is rather likely to survive a wildfire unbothered if the ground a couple feet around it is kept cleared.
They're simple (not a lot of corners for burning things to wedge in), they tend very well sealed with smaller windows (so less chance of a window breaking and allowing embers in), and the amount of thermal energy it takes to light a full log on fire is quite high. Radiant heat from a forest fire isn't going to bother a log cabin. It might darken the wood somewhat, but it won't light smooth logs on fire. Even random firebrands and such lack the energy to bother wood.
The only concern would be a shake roof - that would catch fire easily and burn the place down. But a well built and "tight" roof (no massive eaves with vents into an attic, just minimal overhangs) of Class A fire resistance would work just fine.
Metal roofing is not inherently fire resistant, either - it depends on the materials, and what's below it. Some metal roofing can transfer enough heat to the wood below to light that on fire, even without direct flame spread. And, non-intuitively, a lot of asphalt shingles are Class A fire resistant when properly installed.
What doesn't work well, obviously, are the sort of expensive homes with "all the architectural features," lots of inside corners that trap debris, and an incredibly complex roofline.
People forget that you don't have to modify a McMansion to whatever requirements you're adding - you can build something entirely different.
"Earthships" or other hobbit-hole like houses are almost completely fireproof as long as the entries are handled correctly - anything that can start a fire through three feet of earth is probably a volcano anyway.
Don't most of those suffer from serious ongoing humidity problems? I've looked into that style of housing in the past, and it seems like it's always having issues with mold, mildew, and ohter "issues of running 90-100% interior humidity for long periods of time" sort of problems. I think they're okay in drier climates - IIRC they were developed in New Mexico, which is "bone dry nine months of the year, and somewhat drier the other three."
A "log cabin amongst the pines" with a decent sized "yard" clearance area, a good roof, and where the sides of the house are kept reasonably moist is pretty much fireproof.
Highly suggest clay tile roofs. They last a hell of a lot longer than metal roofs, which have several of their own problems.
As a British citizen by birth, I'm amused by the idea that Americans may get National Insurance for houses before they do for healthcare.
It does seem to be backward. In my opinion, "insurance" is strictly about compensation for loss, and should absolutely be a private transaction, while preventative and emergency systems should probably be public. Healthcare coverage, despite being called "insurance," is really a system of preventative and emergency services, while California's state-run home insurance is the former. But this is what they get for trying to have price controls.
We have plenty of national insurance programs, including for both of those... but they're not both free and universal.
https://en.wikipedia.org/wiki/National_Flood_Insurance_Progr...
That's a great point. We'll get public insurance for houses only if the legalized bribery paid by existing insurance companies to block public ins. is less effectively applied than the money blocking public health insurance in the US. Old people don't care because they have medicare at 65+, while the rest of us slubs are going along with whatever we can find.
We get what we allow or deserve here in the US. Citizens United led to our current awful outcome.
Public insurance would provide no benefit. The issue in California is that people have built their houses in dangerous areas and have not taken any measures to reduce fire risk. The state has already set limits to how much insurance costs can be increased (from a past generation of economic illiterates who wanted to stop "middlemen siphoning value"). Therefore, insurance companies are just pulling out, which disproves the entire idea that they are "siphoning value", since obviously there is no value there to siphon.
The only thing that public insurance would do is to provide a way for the state to incur another massive unfunded liability. Except, unlike healthcare or pensions which have the somewhat laudable goal of taking care of poor people and old people, this would go to bailing out rich homeowners who made a bad investment of a house in a flammable area and then refused to spend money on fire safety measures, either in their home or their municipality.
Of course these fire zone bag holders are now clamoring for the state to take on their bad investments by pushing conspiracy theories about the evil insurance companies.
The danger of the areas has not been properly accounted for, and now that we have a better understanding, nobody wants to pay what it actually costs (either in increased insurance, which apparently CA has limited, or building design changes - knock down the flammable one and build something impervious, or even abandoning untenable locations - perhaps after disaster, perhaps before).
Everyone's talking about fire insurance, but the earthquake insurance question is even bigger and basically untenable in a worst-case scenario. So in that case, CA wised up and the state is much more earthquake resilient than it was 30 years ago.
Not sure I agree with housing insurance as a public service… we do want to expose some risk to drive behavioral changes. People really shouldn’t be building houses in low lying areas near the shoreline in Florida. But if there’s no risk because it’s covered by other tax payers, then they will.
> Public insurance.
That only guarantees you have insurance. It does not guarantee that you will be covered or made whole in an incident or emergency.
See FL Citizen's insurance and other insurances of last resort as examples.
What really needs to happen is premiums go up with the cost of risk. But this also means pricing people out of homes, vehicles, businesses, etc. And no politician will allow this.
Only pricing them out of unsafe homes/cars etc. I feel like that is probably a good thing.
It does seem like it's time to stop letting this "industry" profit off the misfortune of its customers. Making all of these a public service instead of private industry makes sense at this point.
The profit margins on insurance are usually pretty slim. Insurance companies are generally not well differentiated from one another, so they have few avenues to compete other than on price. A state-run insurance plan also has to operate at a profit/surplus or else it will have to be subsidized by the taxpayers. The effect is the same either way.
Slim from a percentage of total premiums but substantial when looking at the absolute dollar amount of profits. It's all relative to the size of the pie.
The absolute value is only meaningful when compared to the amount of capital invested.
Its also only meaningful when measured over a long period which takes good years and bad years into account.
Also, when margins are slim, a major event (like a series of wildfires in one of the biggest cities in the US) can wipe out those profits. A responsible insurer can withstand one bad year. But if those major events start happening with more frequency, then one bad year becomes a series of bad years. Reinsurance premiums for the insurer go up, meaning that taking on risk is more expensive, and they’ll eventually have to decide between raising their own premiums to unsustainable levels or pulling out of risky markets.
Ironically they don't profit off the misfortunate customers. Those ones typically get back more than their premiums.
They profit off the fortunate customers, those who have no need to claim from insurance.
It’s regulated, not illegal.
“Experts say the insurance landscape in California is particularly tricky because, in addition to the wildfire risk, the state has a law that adds extra approval measures, including board approval and review by the insurance commissioner, if an insurance company wants to raise the rate of insurance by more than 7%. That’s been in effect since the 1980s.” https://www.cnbc.com/2024/02/05/what-homeowners-need-to-know...
Illegal seems fine as shorthand though. Same with housing -- "illegal" to build in many instances. Not technically illegal of course, but enough hurdles makes it effectively so.
If it's not permitted to raise the price of premiums to point where it covers the actual risk, then it's de facto illegal. Nobody will sell insurance policies at a loss.
I don't think it is incompetence of the governments. It appears to be a goal of most US politicians to add to the coffers of private business, insurance companies included, at the expense of all but the most rich Americans.
I'd finish your comment with "it's a goal of most US politicians ... to enrich the most wealthy Americans".
I recall reading somewhere that the Indians had done controlled burns before Europeans settled in the parts of the U.S. where fires are now a problem. European settlers who displaced them did not continue the controlled burns and then fires became a problem. Apparently, if you do regular controlled burns, the severity of fires is reduced and healthy trees survive it. When you do not, when fires do occur, all trees die and the fires spread out of control.
I recall reading the same thing, however I do recall that they were East coast native Indians, that cleared oak tree forests as a hunting grounds, so completelly unrelated to the problem in California. The story was about native land rights and if such looking after their hunting grounds can be seen as claims on property rights, which Indians did not knew as a concept, so it is a moot point anyway. The issues that plague CA seems to be chaos in organization level - from what I have read these wildfires are happening in the year, that did had moderate drought(compared to others), so I would look suspiciously in this with the mind, that if politicians are blaming climate, then it is a sign that they are absolutelly responsible for what they have not done and promised to people. But I do not own a house there and I have not voted for these people and I absolutelly would not hang them in the chimney of my house.
PS Also, there are many opportunists, that were burning their houses to receive insurance or compensations, so not all of those houses were burned by wildfires. It all looks ugly, regadless from what angle you look, because if there is no responsibility - even from the ones that have taken upon resposibility, then catastrophe is expected - sooner than later.
I thought that the idea that they did not understand property rights was a misconception. The different tribes had their own territories, and they clearly had an idea of the territory belonging to one or another. This is also why people negotiating with them for land would use underhanded negotiating tactics such as getting their leaders drunk for the negotiations so that they would agree to absurd deals. If they did not understand property rights, there would have been no point to doing that.
We had a lot of rain the last couple of years (before 2024), which got us out of severe drought for several years back into "moderate". 2024 has been QUITE dry, relatively speaking, but because of the previous years of a LOT of rain, it's only back to moderate drought status, AFAICT.
The years with lots of rain caused MUCH extra plant growth, and anyone who's been here a while expected several bad fires during our fire season in 2024 as the first "dry" year after a "wet" year. The fact that it's only been 1 major one and a few minor ones has actually been a bit of a surprise.
Yosemite NP, especially the iconic valley, looked vastly different when the Europeans first arrived in the nineteenth century. It was sparsely forested and had lots of meadows. After a 150 years of no controlled burns, it's a dense forest down there. It turns out the native peoples were managing the forest, after all.
The national park service does controlled burns in Yosemite and has for a couple decades at this point. You can argue they don't do enough but they're limited by bureaucracy, safe conditions, and manpower rather than willingness.
> East coast native Indians
This is false. Fire was unambiguously part of the practice of native Californians.
> opportunists
What is this slander.
I recall seeing a documentary on TV about this. Indigenous Americans were behind the effort to resurrect the practice.
https://www.nps.gov/subjects/fire/indigenous-fire-practices-...
> The truth is that the rich diversity and stunning landscapes of places like Yosemite and other natural environments in the United States were intentionally cultivated by Native Americans for thousands of years. And their greatest tool was fire.
Theory: Damages in the USA have gone up because mold mitigation was incorporated as a serious consideration only fairly recently. If you increase your definition of what damage is and the work required to fix it then 'damage occurring' will appear to suddenly go up.
Wildfires are not the problem. They happen all the time without causing billion-dollar insurance claims. Insurance is always assets x risk. The issue is expensive flamable housing (assets) in a wildfire area (risk). We ask for trouble when we create million-dollar wooden houses surrounded by manicured gardens in desert enviroments. And build on a slope facing pervailing winds. The answer is concrete/brick houses with metal/ceramic rooves surrounded by sand/stone/concrete. Want a big green lawn? Move to the pacific northwest. Want to live near the beating heart of the movie industry, a town where it never rains? Get used to cactuses instead of rose gardens.
That doesn't align with the reality of these areas. To get insurance in these areas you have to demonstrate that you have created a defensible space around your house. This is enforced by local fire department inspections. I know this because I live near a fire prone area. Despite these things the area still burned. The problem isn't "lawns" or "wooden houses". In the case of the LA fires you would have had the burned out husks of concrete houses that would need to be demolished if everything was made of concrete. This was a black swan event that will require a thoughtful response.
From the recent events in California I have seen many photos of burnt houses with unburnt trees around. I think those houses were especially flammable more than some vegetation around it seems. After the fire nothing remained but the chimneys. I have never seen any house burn like that in Europe.
I live along the Mediterranean sea in France, many wood fires every summer, with wind above 100km/h; never seen so many houses burn like in California even when most of our houses are concrete but with wooden framework.
I'm pretty sure that if houses were built like here (concrete / concrete blocks with terracota tiles on wooden framwork) at lot less would have burnt. Maybe those near the wooded slopes but not in the middle of a neighborhood block.
> From the recent events in California I have seen many photos of burnt houses with unburnt trees around.
I think some of that can be attributed to the fact that buildings are stationary structures that have ample square-footage for embers to land and cause fires, where as trees have less stationary surface area for embers to land, remain and build into fires.
I have looked on some videos of how those good looking US houses have plastic drainage, plastic material roof cladding and plastic panels inside and outside. And the first thing that I was thinking - those burn in an event of house fire. But I see more ond more building materials that were used in US now offered and being standard in building here in Europe, so most probably some of the newer houses in an event of fire will burn down in similar fashion. I'm just wondering if the commenter that mentioned "black swan event"(a very popular theme in Russia and unrelated to wildfires) actually understands that USA has plastic houses everywhere and nothing will change - new mansions will be rebuilt in burned areas with the same materials, but because they are going to offer them as fireproof branded, they will cost more. That's all - these areas won't be abandoned, because location, location and location is the only thing that matters in property business and in your property value.
The Grenfell tower fire comes to mind regarding flammable cladding. Not "new" but "renovated".
It killed more than 70 people.

What does this mean, "popular theme in Russia"
> along the Mediterranean sea in France, with wind above 100km/h
And what's the humidity?
The Santa Ana winds that affect LA are extremely dry and gusty with < 10% relative humidity. It is hard to compare them to anything else.
Yeah, but it's California, so I'm not sure concrete is great for the earthquakes.
The reality is the fires didn't make it far into the city grid sections of LA proper. This is because these areas have less flammable material, and are more defensible.
> Despite these things the area still burned.
I suspect the rules for making a defensible house were wrong. For example, I read an article recently that posited that most of the fire was spread by burning embers on the wind, and not by intense heat from nearby flames.
The idea is to look at where embers accumulate and eliminate or fireproof those areas. For example, a low masonry wall a few feet from the house can stop a lot of heavier burning embers from piling up against the house. If you've got a swimming pool, add a pump to it that feeds sprinklers in the yard and on the rooftop.
There are a lot of homes that did not burn - look at them and figure out why they didn't burn.
For a related example, every airplane crash is looked at, and we always discover overlooked vulnerabilities. The tsunami that devastated Japan a few years ago also provided a lot of information about what worked and didn't work.
We're a long way from needing to give up. There's a lot of low hanging fruit.
Sure, but that's how it already works. The airplane example is how building codes generally work. London didn't rebuild in wood after the Great Fire, to give an ancient, and large-scale, example.
From what I've read, the houses in LA that did survive were modern or heavily remodeled houses incorporating recent code changes to prevent embers from entering the eaves and suchlike.
It really doesn't help that most of LA was built up in the early to mid 20th century; requiring code updates during remodels can only help so much, because if the cost/change is too much/invasive the homeowners either don't remodel at all or do it without permits, bypassing the more costly safety improvements.
>This was a black swan event that will require a thoughtful response.
Taleb would have a field day with this one. Broadly, I think a big part of the argument is driven by the assumption that the area will be rebuilt, despite being a known fire risk.
Because of the Santa Ana winds (with this apparently being more than usual), you'll continually have very dry conditions with high winds and the danger of a fire getting out of control. I don't see it as a black swan either. This is a repeatable scenario, every few years they'll probably have conditions like this. The climate is changing, maybe this will spread or move to areas nearby.
I live in an area that had a special warning last summer, we had a very very dry summer and there was a period with low humidity and high winds for a few days, it was considered an unusual scenario with extreme fire risk - but nothing happened this time. Now that I'm writing this I'm wondering what I'll do if it feels like an annual occurrence. Another parallel, the power company warned us they might shut off the power to reduce risk but I guess it didn't get that bad.
You need only like 10 meters of concrete to stop any fire. Just build the houses inside.
I've seen fires skip valleys miles wide.
Are you suggesting we build houses inside concrete cubes with walls 10 m thick?
Those protections are all about keeping a structure from catching fire. That is different than designing a structure not to burn. A wooden house surrounded by fire protection is OK under current rules. But it is still wood and will, eventually, burn when faced by a wild fire on all sides. A house built out of rock/brick/concrete/sand will not. We need to go beyond flamability and start reducing the actual number of calories availible to be burned.
Why is the answer not Japan's approach. My understanding is that because of high incidents of natural disaster they see/build homes as transient and utilitarian rather than as long-lasting investments.
Partially because that story about Japan is incorrect.
In reality, it is Japanese condos that get gutted periodically or when sold, and it's driven by their real estate tax code.
Japan takes enormous effort to prevent and mitigate natural disasters.
There may have been some truth to it 200 years ago, with the idea that wood was the only economical way to build a house that could last.
A forward looking (part of a) solution for Malibu would be the county acquiring and maintaining beach paths every few houses. Prescribed 10' wide fire breaks.
This solves the fire problem AND the limited access to a public resource that is common in Malibu.
Ideally a permeable surface without any growth, cleared at least 2x a year.
Legal Eagle claims that embers can travel up to 2 miles:
https://youtu.be/5h1H36rdprs?t=1m51s
That would easily jump a 10' fire break.
houses however, survived with much smaller fire breaks.
https://m.youtube.com/watch?v=yZe-TlYxm9g&pp=ygUkaG91c2VzIHR...
especially for this fire, jumping doesnt mean that everything 2 miles down wind also burned down. buildings that far had the opportunity to burn, and if they dud, had the opportunity to burn their neighbors, and another 2 miles down.
i imagine ember density is more interesting than distance?
That would only account for the small amount of homes right on the beach itself - the majority of Malibu is in the hills above
I would prefer no bailouts.
If insurance wants firebreaks for insurance, that is their choice.
If the city wants buy RE for access, that is between tax payers and the land owners. Cash talks
> the county acquiring and maintaining beach paths every few houses. Prescribed 10' wide fire breaks
Ooh, and make a bailout conditional on homeowners (or counties) agreeing to eminent domain.
That would not have solved the problem in this fire since wind speed was so high. The videos showed embers traveling far and fast. Having a 10 foot fire break would not have prevented the spread. One thing to look into is how the fire started and if the electrical equipment can be made safer, like being underground in some places.
The break would need a low masonry wall to stop embers from being pushed along the ground.
Wildfire structure losses can be mitigated with cutting firebreaks, building material selection and removing flammable trees and plants from properties. A lot of communities in western Canada have learned this the hard way.
Where is “here”? Are you sure you aren’t confusing hurricanes and tornados? Hurricanes rarely destroy houses in the US, either.
How are you making this claim? Every time a hurricane hits Florida, there are photos of entire neighborhoods devastated by wind and storm surge. How many people were permanently displaced by Katrine? Etc. Maybe many of the homes weren't technically "destroyed", but each storm brings millions or billions in damage.
Hurricanes are common. The general case is they hit hundreds or thousands of square miles and destroy none or at worst a tiny fraction of the homes they hit.
Take Katrina from my friends and family living in New Orleans, you’ll find city streets where none of the houses go significantly damaged. They lost power long enough you don’t want to open the fridge, but most of the city was fine in the hardest hit city from one of the most expensive storms on record.
Over 200,000 homes were damaged or destroyed in Katrina:
https://en.wikipedia.org/wiki/Reconstruction_of_New_Orleans
Not sure how that is a "tiny fraction" of homes. $125 billion in damage (2005).
Moving the goalposts from destroyed to damaged gives different results.
The issue is most to the city only sustained water damage, a solid chunk of the city is above the water level and was absolutely fine. Moving outside the city most homes in Louisiana, Texas, Alabama etc don’t need to worry about flooding.
A lot has to do with infrastructure.
In most of South Florida basically anything left standing is pretty well built to withstand hurricanes.
A category 1 storm hitting NYC or North Carolina is an unbelievable disaster. A category 1 storm hitting Broward County is usually disruptive to everyday life but that’s it.
Hurricanes usually don't affect the structure of a house. They might damage the roof, parts of exterior cladding, perhaps windows, and the flooding which accompanies hurricanes destroys personal possessions, interior furnishing, electrical wiring, and appliances.
In the US, manual labor is very expensive, home construction or repair is highly regulated and requires permits and multiple inspections from the local government, and the amount of flood-destroyable stuff - material possessions, furnishings, appliances - in a typical home is massive. As a result, a cyclone which a poorer country would survive with a shrug in the US becomes an extremely expensive disaster.
It sounds like we're quibbling over the definition of "destroyed"... if a home is rendered uninhabitable for days/weeks/months, I'd consider that "destroyed" even if the framing is in fact salvageable.
And certainly as it relates to insurance, the trend sure seems to be well on it's way towards "coastal Florida is insurable" (either the price goes up beyond the means of the residents, or the insurers leave the market). Something like 5% of the state is covered by Citizen's Property (the government insurer of last-resort). Some coastal areas are ~10%. I have to imagine it won't be long before it's cheaper to pay people to move elsewhere than rebuild where they are.
adaptation to hurricane winds has largely been done in many parts of Florida; adaptation to storm surge is possible and some cities are beginning to.
the issue for Florida is that the state is made of permeable limestone, so it’s not possible to engineer around sea level rise. not so much an insurance issue exactly though, because it’s not a one-off disaster.
Good to know. The news always seems to find footage of destroyed suburbs whenever the US is hit by a big one.
It's so interesting to see the people in awe of that "fire hurricane" video in L.A....
We had a way more intense drought than they in my city last year (theirs are not that intense). We also had 50 km/h winds. We also had higher temperatures... And all of those to levels that we never saw before. Also, we have more trees in our cities. We had new "fire hurricane" videos every week (normally, every other year somebody films one).
And we had to evacuate dozens of homes, luckily no one was destroyed and people could return 2 months later.
It rather blunts your point when 50km/h winds are a far cry from 160km/h winds.
Specifically, I'm now questioning if your drought was actually more intense. Not exactly sure how you measure that one.
You’re comparing apples to oranges.
A Santa Ana wind is extremely dry and this one hit 100kmh (not 50). And it hasn’t really rained for 8 months (since May 2024). And we had a very wet winter last year, so there’s extra growth to fuel any fire. And finally, there’s 10 million people live in LA County, it’s a target rich space.
Please let me know where else is having the same sort of fire without destroying homes.
The 50 km/h was sustained, not peak, but ok, I don't think we reached 100.
We have 7 million people living around, and yeah, only 6 months without a single drop of rain (19X days, where I don't remember what X was). Fire often destroys some homes, we got luck last year.
It's not a competition. Both can be sights that people view in awe. Are you "Four Yorkshiremen-ing" wildfires?
Look, the annual fire disasters in California are not a normal thing.
If people just point out it's not normal, people complain that nowhere else has fire so nobody else understands the problem. If people point out similar places, looks like it's "Four Yorkshiremen-ing" (whatever that is). So, yeah, let it keep burning, whatever.
