> 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.

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.

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.

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.
