    A catastrophic magnitude 8.2 earthquake off the coast of Ecuador and Colombia generated a strong tsunami that killed 500 to 1500 there. It was observed all along the coast of Central America and as far north as San Francisco and west to Japan.....The wave arrived in Hilo at about 12.5 hours after the earthquake. It covered the floor of the old wharf at the end of Waianuenue Street and the railroad tracks between there and Waiakea. The range of oscillations in water level was 3.6 m and the perio

    A severe and locally damaging tsunami generated on Kamchatka by a magnitude 8.2 earthquake struck the Hawaiian Islands at 1:00 P.M. Property damage from these waves was estimated at $800,000 to $1,000,000; however, no lives were lost. The waves beached boats, caused houses to collide, destroyed piers, scoured beaches, moved road pavement, etc. A farmer on Oahu reported 6 cows killed.

On Umnak Island, part of a dock was destroyed, and Mount Vsevidof erupted after being dormant for 200 years. Further, this shock generated a 15 meter tsunami that smashed into the coastline at Scotch Cap and an 8 meter tsumani that washed away many buildings and damaged oil lines extensively at Sand Bay.

    Lituya Bay, a ⊺-shaped tidal inlet on the northeast shore of the Gulf of Alaska, heads in the trench along the Fairweather fault. Displacement along this fault at the time of the earthquake of July 9, 1958 (local time), triggered a rockslide into deep water in Gilbert Inlet, one of the two arms at the head of Lituya Bay. The rockslide, with a volume of 40 million cubic yards, caused water to surge to an altitude of 1,740 feet on a spur opposite the point of impact, and generated a gravity wave t

    The great Kurile Islands underthrusting earthquake (Mw = 8.5) of October 13, 1963, was accompanied by a large foreshock and an aftershock. This sequence allows us to investigate the rupture process and fault heterogeneities along a subduction zone. We have characterized the rupture process of the main shock event by deconvolving long-period P wave seismograms from azimuthally well-distributed stations to obtain source time functions. Directivity associated with the three main pulses of moment re

    On Adak Island, cracks occurred in prefabricated wood buildings; on Shemya Island, cracks were observed in an asphalt runway. Hairline cracks also formed in the runways at the U.S. Coast Guard Loran Station on Attu Island. This earthquake generated a tsunami reported to be about 10.7 meters high on Shemya Island. Loss caused by flooding on Amchitka Island was estimated at about $10,000. An aftershock at 07:40 UTC was assigned MMI VI.

The quake was the second strongest ever recorded since .1900, with a Richter magnitude of 9.3 according to Northwestern University, though the .USGS suggested a magnitude of 9.0. The epicenter was 155 km west of the Indonesian .island of Sumatra. The earthquake resulted from the rupturing of the subduction zone between the India plate and the overriding Burma microplate with a vertica

This 8.7 magnitude earthquake came only three months after the devastating magnitude 9.0 earthquake of December 26, 2004 which occured in the same region. This earthquake damaged hundreds of buildings throughout the region and killed over 1,300 people and injured more than 500. The earthquake spawned a tsunami that reached heights as much as two meters.

    The magnitude 8.4 and 7.8 southern Sumatra earthquakes of September 12, 2007 occurred as the result of thrust faulting on the boundary between the Australia and Sunda plates. At the location of these earthquakes, the Australia plate moves northeast with respect to the Sunda plate at a velocity of about 60 mm/year. The direction of relative plate motion is oblique to the orientation of the plate boundary offshore of the west coast of Sumatra. The component of plate-motion perpendicular to the bou

    During September, the Yakutat Bay region was shaken by a series of severe earthquakes. The first earthquake at 00:22 UTC was moderately strong at Yakutat but was extremely violent at Cape Yakataga, about 160 kilometers west. The shock broke off the tops of trees, generated landslides, and raised the ocean beach about 1 meter. Although no loss of life or property occurred in the region, reported effects include uplift of the coast, landslides, difficulty in standing upright, water waves on the ba
