The media has been reporting various small quakes over the last week. But is that really something to worry about? "It’s not uncommon for Orange County to experience several microquakes every week," Sciencedude Gary Robbins said at the OC Register in a brief about the three recent microquakes in Orange County. His statement goes for all of Southern California -- small quakes happen all the time. A daily viewing of the USGS' recent earthquake map shows this or event better, the agency has gotten hip to Twitter and publishes a feed called "socalquakes." They also publish "Earthquake News," which combines shakes worldwide and headlines. more ›

Hollywood studios are not the ones behind the latest script detailing a massive future earthquake hitting Los Angeles. This time, it's scientists and other quake experts... over 300 of them.

It's a full moon and the earth is shaking. Three small quakes within a hundred miles of Los Angeles in the past hour alone, according to the U.S. Geological Survey Web site.
