摘要

Latin American countries share similar history and culture, and complicated tectonic settings. Subduction of the Rivera, Cocos, and Nazca plates had produced 23 M ≥ 8.0 subduction and intraplate earthquakes since 1900 when seismic instrumentation took off. This seismicity includes the 22 May 1960 M_w 9.5 Valdivia, Chile, earthquake, the largest ever recorded in the world; and the most recent intraplate M_w 8.2 earthquake in the Gulf of Tehuantepec, in southern Mexico. Subduction is also present to the east of the Caribbean plate with earthquakes of M ≥ 7.0, including some historical megathrust earthquakes (Robson, 1964). In addition, 18.6% of the large deep earthquakes (M ≥ 6.0) in the world have occurred in South America, including two of the largest (31 July 1970 M_w 8.0 in Colombia and 9 June 1994 M_w 8.2 in Bolivia). Seismic hazards in the region are also associated with transform faults earthquakes (M ≥ 7.0) that take place at the boundaries between the North American plate and the Pacific and the Caribbean plates; as well as the South American plate and the Caribbean and Scotia plates. Other significant earthquakes have occurred in the region, such as the Nicaragua tsunami earthquake (2 September 1992 M_w 7.7) and the destructive Haiti earthquake (12 January 2010 M_w 7.0). In fact, in almost all countries in the region, there is at least one earthquake that has had a significant impact on the society, infrastructure, and economy.
