Here's a Google Earth Placemarks file for a series of minor and micro earthquakes
that occured in late December 2006 (last one in file, magnitude 3.5, December 23, 9:21 am PST): Download here.
"Save as..." the file, then open with Google Earth. Firefox users will be able to just click on this link and have Google Earth open. (Last updated
7 Jan 2007 with 1.2 magnitude quake near Clayton. Hayward Fault line also added. I've added earthquakes in the greater
SF Bay Area.)
