Some Interesting History Behind The LA Fires - This Same Kind Of Fire Happened 63 Years Ago

in Technicolor, no less...

Here -\

Stick built houses with asphalt roofs and OSB underlayment up on top of hills or at the ends of arroyos and canyons - lots of oil- and resin-rich mesquite and eucalyptus, lots of dried out hot-burning brush - makes a natural blowtorch hot enough to make steel white and yellow hot, the difference between 63 years ago and now is that there are a lot more buildings - stick built and with asphalt or wood shingle roofs - in places where such buildings ought not be built, side by side and close up so that a chain reaction fire is an easy thing to happen. So there’s history here, and errors were compounded and not learned from - will people do the same thing yet again?

This, too - and the twenty-year fuel accumulation cycle repeats -

Interesting note: In Australia, bushfires are common and they use steel roofs to protect dwellings against it - and have done extensive research, see https://research.csiro.au/bushfire/new-builds/roofs/ and https://research.csiro.au/bushfire/assessing-bushfire-hazards/bal-assessment/ and for general guidelines for new construction - https://research.csiro.au/bushfire/new-builds/ -
