Ah, my humblest apologies. Apparently my reading comprehension skills are not up to snuff. I'm so gosh darned thick I read your posts and not only thought you made numerous references to weather being a factor but also very quickly defended your assertions. Obviously, I was grossly mistaken. A thousand pardons. Thanks for getting me back on track.
As a way of recompense can I perhaps assuage your fears about trees? Maybe I can provide you some piece of mind?
What a tree experiences in an earthquake is the direct effect of the seismic wave passing through it. This is generally less of a force on a tree than moderate wind conditions.
Liquefaction is, of course, an exception. However the liquefaction potential for most of Gilroy is low.
Also, damage during Loma Prieta was relatively mild in Gilroy. There were more red tagged building in Sunnyvale and Mountain View and Los Gatos was much harder hit than Gilroy. How do I know? I was working in Santa Cruz at the time and we did much of the clean up of red tagged structures and transportation facilities in the South Bay. I was assigned to Watsonville (which was obliterated) and Gilroy (which was not) along with the Highway 152 corridor.
In other words, falling trees are more of a risk in high winds than in an earthquake...and the soils in Gilroy are generally NOT susceptible to liquefaction.
