California Quaking.

The article reports that every day, several of California's more than 1000 shifting faults shake some part of the state. This clearinghouse of earthquake data keeps check on the ones that rattle northern California. Sponsored by the University of California, Berkeley, and the U.S. Geological Survey, the site catalogs magnitude, depth, location, and other measurements for earthquakes dating back to 1967. One should check out near-real-time recordings from a network of seismographs scattered around northern and central California.
