Earthquakes
An earthquake is a sudden and sometimes catastrophic movement of a part of the earth's surface. Earthquakes result from the dynamic release of elastic strain energy that radiates seismic waves. Earthquakes typically result from the movement of faults, planar zones of deformation within the earth's upper crust.
Scientists in the Cecil H. and Ida M. Green Institute of Geophysics and Planetary Physics at Scripps Institution of Oceanography conduct numerous studies of Earth, including research on earthquakes that occur in its oceans, as well as on land. Scripps researchers operate the global IDA Seismic Network and a geophysical observatory near Palm Springs. Earthquake research has been under way at Scripps for decades as scientists are attempting to understand why earthquakes occur and where they are most likely to strike.
