Earthquakes; September-October 1983

Two major earthquakes (magntidue 7.0-7.9) occurred during the month of October. The first was on October 4 in northern Chile. the second occurred in the United States in the State of Idaho on October 28. This was the first major earthquake in the conterminous United States since a magnitude 7.2 event occurred near the coast of northern California on November 8, 1980, and was the first earthquake to cause fatalities in the conterminous United States since February 9, 1971.

The Great Tumaco, Colombia earthquake of 12 December 1979

Southwestern Colombia and northern Ecuador were shaken by a shallow-focus earthquake on 12 December 1979. The magnitude 8 shock, located near Tumaco, Colombia, was the largest in northwestern South America since 1942 and had been forecast to fill a seismic gap. Thrust faulting occurred on a 280- by 130-kilometer rectangular patch of a subduction zone that dips east beneath the Pacific coast of Colombia. A 200-kilometer stretch of the coast tectonically subsided as much as 1.6 meters; uplift occurred offshore on the continental slope. A tsunami swept inland immediately after the earthquake. Ground shaking (intensity VI to IX) caused many buildings to collapse and generated liquefaction in sand fills and in Holocene beach, lagoonal, and fluvial deposits.
