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.
The inclusion criteria for adding events are based on WikiProject Earthquakes' notability guideline that was developed for stand alone articles. The principles described are also applicable to lists. In summary, only damaging, injurious, or deadly events should be recorded.
The 1960 Valdivia earthquake and tsunami or the Great Chilean earthquake 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, while some studies have placed the magnitude lower than 9.4. It occurred in the afternoon, and lasted 10 minutes. The resulting tsunamis affected southern Chile, Hawaii, Japan, the Philippines, eastern New Zealand, southeast Australia, and the Aleutian Islands.
The 1575 Valdivia earthquake occurred at 14:30 local time on December 16. It had an estimated magnitude of 8.5 of on the surface-wave magnitude scale and an estimated magnitude of 9.0+ on the Moment magnitude scale and led to the flood of Valdivia, Chile.
Orca Seamount is a seamount near King George Island in Antarctica, in the Bransfield Strait. While it is inactive, last volcanic activity at Orca Seamount is judged to have occurred in the recent past as there are temperature anomalies in the seawater around the seamount. Thermophilic and hyperthermophilic microorganisms have been found at the seamount.
The 2010 Chile earthquake and tsunami occurred off the coast of central Chile on Saturday, 27 February at 03:34:12 local time, having a magnitude of 8.8 on the moment magnitude scale, with intense shaking lasting for about three minutes. It was felt strongly in six Chilean regions that together make up about 80 percent of the country's population. According to the United States Geological Survey (USGS) the cities experiencing the strongest shaking—VIII (Severe) on the Mercalli intensity scale (MM)—were Concepción, Arauco, and Coronel. According to Chile's Seismological Service, Concepción experienced the strongest shaking at MM IX (Violent). The earthquake was felt in the capital Santiago at MM VII or MM VIII. Tremors were felt in many Argentine cities, including Buenos Aires, Córdoba, Mendoza, and La Rioja. Tremors were felt as far north as the city of Ica in southern Peru. It is the largest earthquake to hit Chile since the 1960 Valdivia earthquake.
The 1985 Rapel Lake earthquake occurred on 8 April at 21:56:59 local time with a moment magnitude of 7.2 and a maximum perceived intensity of VI (Strong). The shock was centered 75 kilometres (47 mi) southwest of Santiago, Chile, with a focal depth of 37.8 km (23 mi).
The 1906 Valparaíso earthquake hit Valparaíso, Chile, on August 16 at 19:55 local time. Its epicenter was offshore from the Valparaíso Region, and its magnitude was estimated at 8.2 Mw. This earthquake occurred thirty minutes after the 1906 Aleutian Islands earthquake.
The 2011 Guerrero earthquake struck with a moment magnitude of 5.7 in southern Mexico at 08:24 local time on 5 May. It was positioned west of Ometepec, Guerrero, with a focal depth of 24 km (14.9 mi), and was lightly felt in many adjacent areas.
The 2010 Pichilemu earthquakes, also known as the Libertador O'Higgins earthquakes, were a pair of intraplate earthquakes measuring 6.9 and 7.0 Mw 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 Pichilemu.
The 1960 Concepción earthquakes were a succession of three destructive earthquakes that happened between 21 and 22 May 1960. They formed part of the foreshock sequence for the 1960 Valdivia earthquake, the largest recorded earthquake in history.
The 2017 Chiapas earthquake struck at 23:49 CDT on 7 September in the Gulf of Tehuantepec off the southern coast of Mexico near the state of Chiapas, approximately 87 kilometres (54 mi) southwest of Pijijiapan, with a Mercalli intensity of IX (Violent). The moment magnitude was estimated to be Mw8.2.
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. Its epicenter was located off the coast of the Valparaíso Region and had a magnitude of 6.9 Mw. On the scale of Mercalli, the earthquake reached an intensity of VII.
