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.
2012 Haida Gwaii earthquake – magnitude 7.8 earthquake with an epicenter on Moresby Island in British Columbia, the second largest Canadian earthquake ever recorded by a seismometer, over 100,000 people were evacuated to higher ground in the state of Hawai'i
The 1960 Valdivia earthquake and tsunami (Spanish: Terremoto de Valdivia) or the Great Chilean earthquake (Gran terremoto de Chile) occurred on 22 May 1960.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, [6] [7] making it the most powerful earthquake ever recorded.
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 discoveries of Earth's tectonic plates, [1] seismotomography imaging technique, [2] observations using space satellites from outer space, [3] artificial intelligence (AI)-based ...

Lituya Bay has a history of megatsunami events, but the 1958 event was the first for which sufficient data was captured and was responsible for the deaths of 5 people. [ 9 ] [ 19 ] [ 17 ] A subsequent analysis to the 1999 one that examined the wider impact of the event found that the rockfall itself was inadequate to explain the resulting ...
The magnitude 9.5 earthquake of 22 May 1960, the largest earthquake ever recorded, generated one of the most destructive tsunamis of the 20th century. The tsunami spread across the Pacific Ocean, with waves measuring up to 25 metres (82 ft) high in places. The first tsunami wave hit Hilo, Hawaii, approximately 15 hours after its origin. The ...
The largest earthquake ever recorded was a magnitude 9.5 on May 22, 1960 in Chile on a fault that is almost 1,600 km (1,000 miles) long. ... Through history, Nankai Trough earthquakes have been ...
