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 ...
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.
SANTIAGO, Chile (AP) — A magnitude 7.4 earthquake struck northern Chile near its border with Argentina late Thursday, the U.S. Geological Survey reported, shaking homes and causing power outages.
The geology of Chile is a characterized by processes linked to subduction, such as volcanism, earthquakes, and orogeny. The building blocks of Chile's geology were assembled during the Paleozoic Era when Chile was the southwestern margin of the supercontinent Gondwana .
The 2015 Illapel earthquake occurred 46 km (29 mi) offshore from Illapel (Coquimbo region, Chile) on September 16 at 19:54:32 Chile Standard Time (22:54:32 UTC), with a moment magnitude of 8.3–8.4. [ 5 ] [ 1 ] [ 6 ] The initial quake lasted between three and five minutes; [ 7 ] it was followed by several aftershocks greater than magnitude six ...
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 ...
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 2014 Iquique earthquake struck off the coast of Chile on 1 April, with a moment magnitude of 8.2, at 20:46 local time (23:46 UTC). [ 4 ] [ 5 ] The epicenter of the earthquake was approximately 95 kilometres (59 mi) northwest of Iquique . [ 1 ]
