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.
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
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 ...
The first earthquake was the most powerful quake — so far — this ... The strongest earthquake ever recorded in South Carolina — and on the East Coast of the U.S. — was a devastating 7.3 in ...
Millions of minor earthquakes occur every year worldwide, equating to hundreds every hour every day. [15] On the other hand, earthquakes of magnitude ≥8.0 occur about once a year, on average. [15] The largest recorded earthquake was the Great Chilean earthquake of May 22, 1960, which had a magnitude of 9.5 on the moment magnitude scale. [16]
The 2023 Al Haouz earthquake was one of the deadliest and the most powerful earthquake ever recorded in modern-day Morocco. The 2024 Noto earthquake was Japan 's deadliest since 2011 , with the towns of Suzu and Wajima largely destroyed.
Lasting four minutes and thirty-eight seconds, the magnitude 9.2–9.3 megathrust earthquake remains the most powerful earthquake ever recorded in North America, [2] [4] and the second most powerful earthquake ever recorded in the world since modern seismography began in 1900. [5]
