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 partially collapsed 21-story O'Higgins Tower, Concepción. The 2010 Chile earthquake and tsunami (Spanish: Terremoto del 27F) [7] occurred off the coast of central Chile on Saturday, 27 February at 03:34:12 local time (06:34:12 UTC), having a magnitude of 8.8 on the moment magnitude scale, with intense shaking lasting for about three minutes.
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 [citation needed] and are shown in the map to the ...
The tsunami warning was later canceled for all countries except Chile and Peru within a few hours of the earthquake. [22] The tsunami warning was canceled for both Chile and Peru at around 4:58 UTC on 2 April. Hawaii was under a tsunami advisory for over 13 hours. [23] [24] On 3 April local time, tsunamis were observed in Japan. [25]
The largest recorded megathrust earthquake was the 1960 Valdivia earthquake, estimated between magnitudes 9.4–9.6, centered off the coast of Chile along the Peru-Chile Trench, where the Nazca Plate subducts under the South American Plate. [26] This megathrust region has regularly generated extremely large earthquakes.
Chile: Earthquake: A magnitude 9.5 earthquake generated tsunamis 15 to 20 metres (49 to 66 ft) in height that struck 1,000 kilometres (620 mi) of the coastline of the Atacama Desert. People fled the area and did not begin to return until ca. 800 BCE; some pre-tsunami settlements were not reoccupied until between ca. 1000 and 1500 CE. [33] [34]
One tsunami fatality in California. M w [36] 5th largest in recorded history. M w [39] Foreshock to the next earthquake on 22 May. M w [40] The largest earthquake in recorded history. M w [41] One of the largest earthquake in recorded history. M w [43] The second largest earthquake in recorded history.
Tsunami. Yes. Casualties. 1 dead. 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 Mw that struck Chile 's O'Higgins Region on 11 March 2010 about 16 minutes apart. The earthquakes were centred 15 kilometres ...
