Heavy rainfall in Hawaii may have triggered 'silent' earthquake, researcher says

Peter Cervelli, who joined the USGS Hawaiian Volcano Observatory last fall shortly after receiving a doctorate in geophysics from Stanford, discusses how researchers have used a global positioning system (GPS) network to detect a "silent" or "aseismic" earthquake. Detecting these slow-moving earthqukes may help predict catastrophic tsunamis in the Pacific.
