Dave, from all of the references I read, when we thought about building, you are right about the roof, EVERY seimic book I read (most printed 2002-2004) stated that for earthquakes, the lighter the roof the better, but we do also have to consider the widespread potential for high wind events....(kind of a no win, eeny meeny miney moe)
Many of the references repeatedly stated things like the more symetrical a structure the better (offset levels and L's or T's in a building layout make for easier fracture zones). Some biggies that were evident on the Kona side, take care when tieing a structure together ie. addition to an older house should be integratal in the connections, brick, block & stone masonery must be reinforced, and any masonary alongside a structure must be tied in. any land build up with retention walls was a good failure point potential (as was seen frequently in the pics from yesterday).
The info I used were all seismic handbooks that industrial architechs use (our old neighbor was one, so I was able to raid his bookshelves before we moved... earthquakes were/are our biggest trepidation, so I spent time researching the buggers)
Aloha, Carey
