Central Coast Earthquake - 22 December 2003

We lived throught a rather disturbing earthquake on December 22, 2003. The epicenter was approximately 40 miles north of our home here in Arroyo Grande and the earth started moving at 11:15:56AM.

I have collected a number of maps and images from that day, and others, mostly from the USGS Earthquake Site. Without this resource, we would have to rely on the news agencies for information...and we all know how accurate that was!!!
