The answer is obviously "no" since there are other parts of the world that don't live on a hurricane highway nor build houses made from firewood in an area prone to wildfires.

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.
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.
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.
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.
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.
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.
“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...
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.
Compare some incidents with, Hurricane Sandy, for example, where it traveled across the span of a thousand miles and lasted a week of damages.
https://en.wikipedia.org/wiki/Reconstruction_of_New_Orleans
Not sure how that is a "tiny fraction" of homes. $125 billion in damage (2005).
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
https://www.americangeosciences.org/critical-issues/faq/how-...
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.
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.
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.
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.
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.
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.
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...
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.
We get what we allow or deserve here in the US. Citizens United led to our current awful outcome.

That would easily jump a 10' fire break.
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.
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.
This is important. Insurance was invented 2000+ years ago but aggressively deploying technology that worsens floods, weather, and fires is only around ~100.
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.
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.

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 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.
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.
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?
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.
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.
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.
Ooh, and make a bailout conditional on homeowners (or counties) agreeing to eminent domain.
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.
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.

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
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.
Are you suggesting we build houses inside concrete cubes with walls 10 m thick?
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.
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.
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.
The insurance companies have done research on the topic (including building giant 'labs' with a large number of fans)
* https://fortifiedhome.org/research/
and have developed standards/techniques that home builders/owners can do to fix a bunch of problems, starting with roofing:

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.
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 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.
Ofc, a sufficiently strong Tornado is destroying everything in its wake. But, they're rare in comparison.
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.
It killed more than 70 people.
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!".
"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.
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.
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.
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.
This is false. Fire was unambiguously part of the practice of native Californians.
> opportunists
What is this slander.
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.
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.
What do you mean by this?
