Photo: Southern California Long Overdue for Quake, Experts Say



A U.S. Geological Survey map shows earthquakes that hit the Los Angeles, California, area between August 6, 2007, and August 13, 2007.

Though the area is no stranger to mild- and medium-strength quakes, Southern California hasn't seen a major upheaval for more than 300 years. That means such a quake is long overdue, experts say—and "the scale of the disaster could be along the lines of Hurricane Katrina."
