"There might be some minor damage in some places (in Alaska), but a significant tsunami and significant damage from something like that is not expected," Snider said. ![]() states of California, Oregon and Washington and the Canadian province of British Columbia were not expected to see any significant tsunami threats, Dave Snider, tsunami warning coordinator with the NTWC, told Reuters. It struck about 91 km east-southeast of Perryville, about 800 km (500 miles) from Anchorage, Alaska's biggest city. local time (0615 GMT Thursday), was at a depth of 35 km. The 8.2 magnitude tremor recorded in July triggered a tsunami watch in Hawaii - with a warning that waves may even reach as far as Australia. It struck about 91 km east-southeast of Perryville, about. Geological Survey (USGS) said the quake, which struck at 10:15 p.m. The Alaska Earthquake Center said it took place at a depth of 43 miles and is an aftershock of the Chignik quake that hit earlier this year. Geological Survey (USGS) said the quake, which struck at 10:15 p.m. Among them was Seward on the Kenai Peninsula, south of Anchorage, where sirens blared and residents were told to move to higher ground. Several Alaskan coastal communities were evacuated following the quake. Geological Survey (USGS) said the quake was at a depth of 20 miles (32 km). ![]() There were no immediate reports of injuries or damage to property.

Display depth and distance using this unit of distance. A series of aftershocks was recorded following the. The Aleutian-Alaska Benioff zone produces thousands of earthquakes each year, most of which are too deep and too small to be felt. When plates snap back into position, the energy from this movement can cause huge waves to form. The quake was centred about seven miles (11km) north of Anchorage, the largest city in the state, according to the US Geological Survey (USGS). In the Alaska Peninsula region, the seismicity abates at approximately 150 miles depth, reflecting the down-dip extension of the Pacific Plate. Japanese public broadcaster NHK reported that there is no risk of tsunami damaging Japan's coast after it said there might be small changes to tide levels.Įarthquakes are the result of sudden movement along faults within the Earth caused by the release of built-up pressure at plate boundaries. Strong seismic reflections from within the Alaska Range orogen north of the Denali fault dip as steeply as 25N and extend to depths as great as 20 km. Officials at the Pacific Tsunami Warning Center scrapped the alerts when it emerged that the threat was not as great as first feared.
