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.
1960 Valdivia earthquake. 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 ...
2014 Iquique earthquake. 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 mainshock was preceded by a number of moderate to large shocks and was ...
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. [1] [2] 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 ...
Historical earthquakes is a list of significant earthquakes known to have occurred prior to the early 20th century. As the events listed here occurred before routine instrumental recordings — later followed by seismotomography imaging technique, [1] observations using space satellites from outer space, [2] use of artificial intelligence (AI) for early earthquake warnings [3] — they rely ...
The Peru–Chile Trench, also known as the Atacama Trench, is an oceanic trench in the eastern Pacific Ocean, about 160 kilometres (99 mi) off the coast of Peru and Chile. [1] It reaches a maximum depth of 8,065 m (26,460 ft) below sea level in Richards Deep (23°10′45″S 71°18′41″W) and is approximately 5,900 km (3,666 mi) long; its ...
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 ...
A pie chart comparing the seismic moment release of the three largest earthquakes for the hundred-year period from 1906 to 2005 with that for all earthquakes of magnitudes <6, 6 to 7, 7 to 8, and >8 for the same period. The 2011 Japan quake would be roughly similar to Sumatra. Earthquakes of magnitude 8.0 and greater from 1900 to 2018.
