In the case of earthquakes with a magnitude of more than 9.0, destruction and devastation can occur within a range of up to 1000 kilometers. The Easter earthquake this past Sunday has caused damages in Imperial Valley. Although earlier earthquakes have been documented—such as significant movement on the southern San Andreas fault all the way back to the 1600s—the earliest reported earthquake in California was on July 28, 1769, noted by members of a Spanish expedition to chart a land route from San Diego to Monterey. 2009. Earthquake catalogs elucidate the behavior of faults and allow for rough estimates of when large earthquakes might occur.

Due to its location on a transtensional section of the Pacific-North American plate boundary, the Salton Trough is a region featuring large strike-slip earthquakes within a regime of shallow asthenosphere, high heat flow, and complex faulting, and so postseismic deformation there may feature enhanced viscoelastic relaxation and afterslip that is particularly detectable at the surface.

USGS shakemap of one of the strongest aftershocks . Since the first velocity pulse was recorded in the 1966 Parkfield earthquake, near-field velocity pulses have been observed in several subsequent large earthquakes, e.g., the 1979 Imperial Valley, 1994 Northridge, 1999 Chi-Chi, and 2008 Wenchuan earthquakes. In the words of the reporter, “Death struck from the bowels of the earth.” All six persons perished under the debris of bricks and wooden beams, as the buildings they were in, or fleeing from, collapsed.
