The critical factor was time, due to the extremely high winds; from what I have seen,lack of water is not an issue. There are photos of azure blue swimming pools within gutted neighborhoods;indeed, one couple survived by immersing themselves for six hours in their pool (evidently emerging somewhat hypothermic!).

I know very little about building fire suppression, but what I do know would indicate that it is far from simple. Little things like propane tanks (some of which are huge), electrical overhead lines, various common combustibles stored in homes, render fire suppression rather tricky, to say the least.

If there is something to be said for reinforced concrete construction, would you be so kind as to furnish references? Such would be quite welcome....
