Dennis,
I can't really tell you which school, but let's say it's the Holser fault side of the mall. It is older and so it isn't from settling and we have hills that are very close and probably have grown out of tectonic action. Also, I wrote about the fresh rock slides in Placerita Canyon on Nov. 28th, which appeared to be much more recent than the Hector earthquake. I don't think anything is imminent, but the signs of that compression are beginning to pop up - literally! Beth
