I was not suggesting that my proposed reserve fire trucks should be used to fight forest fires in open country.

My suggestion was for a reserve fleet of simple fire trucks equipped with basic equipment that can be employed to fight fires that are threatening built up areas.

It seems to me that many properties burnt that could have been saved with a sufficiency of water, and basic equipment with which to apply the water.
If at least every other home had a full pool, and an extra six basic fire trucks each with basic equipment, could be called on, that should help.

As regards construction that is fire resisting AND earthquake resistant, there is a great deal to be said for hollow concrete block construction.
The blocks are laid in the usual way, and then when the walls are complete, but before the roof is put on, vertical reinforcement is added inside the blocks at stress points.
