Find out how researchers are improving earthquake forecasts in this video from NOVA scienceNOW: "What's the Next Big Thing?" Correspondent Kirk Wolfinger meets with geophysicist Ernest Majer, who demonstrates how his team measures seismic signals that could serve as a possible warning sign for earthquakes. Thomas Jordan, of the Southern California Earthquake Center, describes how hundreds of scientists have joined forces to produce a comprehensive earthquake forecast for California that estimates earthquake sizes, locations, and frequency. A computer simulation illustrates how tremors would propagate from the San Andreas fault across Southern California, showing which communities are most at risk.
