1964 Alaska earthquake and tsunami 1700 Cascadia earthquake
title: 1964 Alaska earthquake text: 1964 Alaska earthquake The 1964 Alaskan earthquake, also known as the Great Alaskan earthquake and Good Friday earthquake, occurred at 5:36 PM AKST on Good Friday, March 27 during a . Across south-central Alaska, ground fissures, collapsing structures, and tsunamis resulting from the earthquake caused about 139 deaths. Lasting four minutes and thirty-eight seconds, the magnitude 9.2 megathrust earthquake remains the most powerful earthquake recorded in North American history, and the second most powerful earthquake recorded in world history. of fault ruptured at once and moved up to , releasing about 500 years of stress buildup. Soil liquefaction, fissures, landslides, title: 2003 San Simeon earthquake text: 2003 San Simeon earthquake The 2003 San Simeon earthquake struck at 11:15 PST (19:15 UTC) on December 22 on the Central Coast of California, about northeast of San Simeon. Probably centered in the Oceanic fault zone within the Santa Lucia Mountains, it was caused by thrust faulting and the rupture propagated southeast from the hypocenter for 12 miles (19 km). The most violent ground movement was within 50 miles of the epicenter, though the earthquake was felt as far away as Los Angeles. With a moment magnitude of 6.6, it was the most destructive earthquake to hit the United States title: 1959 Hebgen Lake earthquake text: from 5.8 to 6.3 were reported after the quake. The earthquake struck in Madison Canyon, an area to the west of Yellowstone National Park. Several nearby campgrounds were occupied by vacationing campers and tourists at the time. Although magnitude estimates for the 1959 earthquake vary (the United States Geological Survey recorded the quake at both 7.3 and 7.5, now calculated by the ISC as 7.2 ) the 1959 earthquake is comparable to the 1906 San Francisco earthquake as one of the strongest earthquakes in North America, behind the 1964 magnitude 9.2 Good Friday earthquake in Alaska. The 1959 earthquake is title: 2018 Anchorage earthquake text: after. Southern Alaska lies at the eastern end of the Aleutian Trench, where the Pacific Plate is subducting beneath the North American Plate. Near Anchorage, the plates are converging at a rate of 57 mm per year. The region has experienced severe earthquakes in the past, including several megathrust earthquakes. The 1964 earthquake, with a magnitude of 9.2, was the largest earthquake in American history and the second largest to ever be recorded anywhere in the world. Though earthquakes are common in Alaska, they often occur out at sea. This earthquake is more similar to the 2001 Nisqually earthquake located title: Reseda, Los Angeles text: the U.S. Bureau of the Census, it has tripled that of the early 1980s. The 1994 Northridge earthquake struck at 4:31 a.m. on January 17 and measured 6.7 on the moment magnitude scale. It remains the only large earthquake to originate directly under a major U.S. city in modern times as well as the most damaging earthquake to strike the U.S. since the San Francisco Earthquake of 1906. Its epicenter was between Arminta Street and Ingomar Street, just west of Reseda Boulevard. This was the second time in 23 years the area had been affected by a strong earthquake. On
