The Aleutian Trench, of the southern coast of Alaska and the Aleutian Islands, where the North American plate overrides the Pacific plate, has generated many major earthquakes throughout history, several of which generated Pacific-wide tsunamis, [22] including the 1964 Alaska earthquake; at magnitude 9.1–9.2, it remains the largest recorded ...
The 1971 San Fernando earthquake (also known as the 1971 Sylmar earthquake) occurred in the early morning of February 9 in the foothills of the San Gabriel Mountains in Southern California. The unanticipated thrust earthquake had a magnitude of 6.5 on the M s scale and 6.6 on the M w scale, and a maximum Mercalli intensity of XI (Extreme).
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.
Earthquake locations are taken from the Centennial Catalog [1] and the updated Engdahl, van der Hilst and Buland earthquake catalog, [2] which is complete to December 2005. From January 2006, earthquake locations are from the United States Geological Survey's Preliminary Determination of Epicenters (PDE) [3] monthly listing.
A magnitude 6.7 earthquake struck Chile, near Valparaíso, on April 17, at a depth of 37 km. [51] One person died of a heart attack and another due to the loss of power at a local hospital. [citation needed] A magnitude 6.8 earthquake struck Papua New Guinea, about 137 km north of Lae, on April 17 at a depth of 208.2 km. [52]
The magnitude 6.2 earthquake that occurred in Joshua Tree, California, on April 22, 1992, was a previously unmapped north-facing earthquake located about 20 km south of the Mount Pinto fault and about 10 km northeast of the mission and a maximum fault slip of 0.8 m (2 ft 7 in) was estimated.
