What I am seeing is the house is burned, but no signs of fire in any of the brush or trees around the house?Let’s see, no defensible space, trees/bushes right up to/overhanging the building, looks like some of the trees are/were eucalyptus (oily torches), no roof top sprinklers or water tank, and the list goes on. Note the house in the upper left has a lawn (defensible space), tile roof and probably stucco walls and is still standing.
Yet I’ve also seen houses with the recommended precautions burn too. The fire, fuel, terrain, and wind ALL have a hand in it.
