It measured 7.87.9 on the moment magnitude scale (Mw), 8.1 on the tsunami magnitude scale (Mt) and 7.4 on the Japan Meteorological Agency magnitude scale (MJMA). This earthquake caused a tsunami that is reported to have killed between 500 and 1,500 in Ecuador and Colombia. 10 Most Powerful Earthquakes in Earth History. The shock occurred in the Aleutian Islands part of the US state of Alaska 19 miles (31km) southeast of Little Sitkin Island. Most of the largest known earthquakes have been centred around the Pacific's Ring of Fire. The waves exceeded 10 meters (33ft) in some areas. 2. Tectonic setting Most coastal towns in the Prince William Sound, Kenai Peninsula, and Kodiak Island areas, especially the major ports of Seward, Whittier and Kodiak were heavily damaged by a combination of seismic activity, subsidence, post-quake tsunamis and/or earthquake-caused fires. At least 49 people died and 100 were injured. The earthquake struck at 12:53 p.m. local time at a depth of 71 miles (114 kilometers), the USGS said. The Survivors out-ran the wave, ascending to high ground. Six hundred miles (970km) of fault ruptured at once and moved up to 60ft (18m), releasing about 500 years of stress buildup. Modelling of the tsunami supports the idea that the earthquake consisted of three sub-events, related to three structural 'blocks' within the overriding plate. No deaths or injuries were reported. I beg the whole world. The earthquake also created around 5,000,000 homeless. These areas of high slip correspond A total of 139 people are believed to have died: 15 as a result of the earthquake itself, 106 from the subsequent tsunami in Alaska, 5 from the tsunami in Oregon, and 13 from the tsunami in California.

AAAS, founded in 1848, has evolved into the world's largest multidisciplinary scientific society with nearly 130,000 members and subscribers. Earthquakes throughout history have inflicted immense damage and proved to be one of the deadliest natural calamities without any doubt. Minor damage to boats occurred as far south as Los Angeles. The great Rat Islands underthrusting earthquake ( Mw = 8.7), of February 4, 1965, represents subduction of the Pacific plate beneath the North American plate along a 600-km segment of the western end of the Aleutian Islands. [1] This was not an aftershock, but a normal fault event within the outer rise of the subducting plate, triggered by the earlier event. It had a magnitude of 8.7 and triggered a tsunami of over 10 m on Shemya Island, but caused very little damage. Optical Illusion for Testing Your IQ: Can you find the Dog with no Spots among Dalmatians in 9 Secs? Here, the Pacific Plate is being subducted under the North American Plate at a dip angle of nearly 45. Land overlooking the Ship Creek valley near the Alaska Railroad yards also slid, destroying many acres of buildings and city blocks in downtown Anchorage. Request Permissions, James N. Jordan, James F. Lander and Rudolph A. The intensity in Petropavlovsk-Kamchatsky was about VIII MSK. Anchorage sustained great destruction or damage to many inadequately earthquake-engineered houses, buildings, and infrastructure (paved streets, sidewalks, water and sewer mains, electrical systems, and other man-made equipment), particularly in the several landslide zones along Knik Arm.
