63-581: SHOA has faced severe criticism after the 2010 Chile earthquake , the largest earthquake since the 1960 Valdivia earthquake. Criticism include the lack of coordination with other authorities and the ONEMI (Chile's emergency office). ONEMI, SHOA and the government have been accused of the initial neglect of the tsunami warning sent by the Pacific Tsunami Warning Center which resulted in the deaths of hundred of persons. The director of SHOA Mariano Rojas

In historical times the Chilean coast has suffered many megathrust earthquakes along this plate boundary, including the strongest earthquake ever measured, the 1960 Valdivia earthquake . More recently, the boundary ruptured during the 2007 Tocopilla earthquake in northern Chile. The segment of

The population grew by 15.63% (31,542 persons) between

630-640: A rate of 80 millimetres (3.1 in) a year. This earthquake was characterized by a thrust-faulting focal mechanism , caused by the subduction of the Nazca plate beneath the South American Tectonic Plates. The end-regions of the rupture zone coincided with the Andean oroclines of Maipo (33° S) and Arauco (37° S). This has been interpreted as suggesting a link between upper plate (South American plate) structure and rupture length. Chile has been at
