Chile lies in a region which is adjacent to the fast-moving Nazca plate, and has high tectonic activity.The records for earlier centuries are apparently incomplete. Of the world's 46 known earthquakes with M ≥ 8.5 since the year 1500, one-third occurred in Chile [citation needed] and are shown in the map to the side.
Map of Valparaíso after the earthquake of 16 August 1906 Area of the city most affected by earthquake City blocks most damaged by fire . Earthquakes, volcanic eruptions and mass ground movements are frequent occurrences. The subduction zone along Chile's coast has produced the most powerful earthquake ever recorded, the 1960 Valdivia earthquake.
The USGS reported that the earthquake resulted from the release of stresses generated by the subduction of the oceanic Nazca plate beneath the South American plate.In this region, known as the Peru-Chile subduction zone, the Nazca plate thrusts beneath South America at a rate of approximately 79 mm/year in an east-north-east direction.
The U.S. Geological Survey said the earthquake struck at 9:33 a.m. local time (12:33 p.m. GMT), and its epicenter was 42 kilometers (26 miles) southwest of Huasco, a city in Chile’s Atacama region.
The 2010 Pichilemu earthquakes (Spanish: Terremoto de Pichilemu de 2010), also known as the Libertador O'Higgins earthquakes, were a pair of intraplate earthquakes measuring 6.9 and 7.0 M w that struck Chile's O'Higgins Region on 11 March 2010 about 16 minutes apart. The earthquakes were centred 15 kilometres (9.3 mi) northwest of the city of ...
