List of earthquakes in Chile. 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 and are shown in the map to the side.
The first one was a magnitude 6.7 M W earthquake that struck off the coast of Biobío, Chile, at 23:21 on 15 March 2010 at the epicenter, at a depth of 18 kilometres (11 mi). The second earthquake struck on land in the region at 22:58 ( UTC) on 2 April 2010 at 5.9 M W and at a depth of 39 km (24 mi).
The 1960 Valdivia earthquake and tsunami (Spanish: Terremoto de Valdivia) or the Great Chilean earthquake (Gran terremoto de Chile) on 22 May 1960 was the most powerful earthquake ever recorded. Most studies have placed it at 9.4–9.6 on the moment magnitude scale , [1] while some studies have placed the magnitude lower than 9.4.
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 2016 Chiloé earthquake with a magnitude of M ww 7.6 struck 225 kilometres (140 mi) south-west of Puerto Montt in southern Chile at 11:22 local time, 25 December. The earthquake triggered a tsunami warning on coasts located up to 1,000 kilometres (620 mi) from the quake's epicentre, generating massive evacuation across the Greater Chiloé Island, after advice from the Chilean government.
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]
The Valparaíso earthquake of April 2017 was a strong earthquake that shook the cities of Valparaíso and Santiago on Monday, April 24, 2017, at 18:38 local time (21:38 UTC ). Its epicenter was located off the coast of the Valparaíso Region and had a magnitude of 6.9 M w. [1] [2] [3] On the scale of Mercalli, the earthquake reached an ...
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 and two ...
