In January 1994, Southern California was rocked by the deadly magnitude 6.7 Northridge earthquake, one of the costliest natural disasters in U.S. history. The quake was preceded by concentrated seismic strain in the region, as detected by space-based technologies like the Global Positioning System. In the decade since, advances in space technology, coupled with new ground-based and computational techniques, have begun to revolutionize our understanding of earthquakes and earthquake processes. NASA's unique contributions to this rapidly maturing field of study and the implications of this research for mitigating future seismic hazards are the focus of the next Earth Science Update Thursday, Dec. 4, at 1 p.m. EST.
