The Richter scale [1] (/ ... 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.
1,000–6,000 [ 5 ] 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 ...
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.
The 1968 Illinois earthquake (a New Madrid event) [ 4 ] was the largest recorded earthquake in the U.S. Midwestern state of Illinois. Striking at 11:02 a.m. on November 9, it measured 5.3 on the Richter scale. [ 5 ] Although no fatalities occurred, the event caused considerable structural damage to buildings, including the toppling of chimneys ...
On March 27, 1964, at 5:36 p.m. AKST (March 28, at 3:36 a.m. UTC), [ a ] a fault between the Pacific and North American plates ruptured near College Fjord in Prince William Sound. The epicenter of the earthquake was 12.4 mi (20.0 km) north of Prince William Sound, 78 miles (126 km) east of Anchorage and 40 miles (64 km) west of Valdez. The ...
The 1906 earthquake preceded the development of the Richter magnitude scale by three decades. The most widely accepted estimate for the magnitude of the quake on the modern moment magnitude scale is 7.9; [1] values from 7.7 to as high as 8.3 have been proposed. [8]
1979 Imperial Valley earthquake – magnitude 6.4 earthquake with an epicenter less than 1 km inside Mexico – significant damage and injuries on both sides of the border (60 in the US) 2010 Baja California earthquake (Mexico near S California) – magnitude 7.2 earthquake, 4 fatalities and 100 injuries, none in the United States.
Magnitude of the earthquake and aftershocks. The 1994 Northridge earthquake affected the Los Angeles area of California on January 17, 1994, at 04:30:55 PST. The epicenter of the moment magnitude 6.7 (Mw) blind thrust earthquake was beneath the San Fernando Valley. [ 3 ] Lasting approximately 8 seconds and achieving the largest peak ground ...
