The second jolt felt stronger to me- but hey, I am right on the fremont Fault and just a couple of miles from the Berkeley epicenter. I took all the pics/glass down in my bedroom (reinforcing better). Frankly, I take being prepared for quakes very seriously. We have a neighborhood org set up to assist elderly and disabled neighbors with turning off gas lines, etc. and ER family contacts, etc. Anyone living in the Bay Area in Ca that doesn't have a plan and supplies for quakes is an idiot and usually the people that screw up effective ways to be safer and aid people that are more vulnerable when these kinds of things happen (the actual "big ones"). Social democracy in action.
