Powerful 7.0-quake causes major damage in Alaska

ANCHORAGE, Ala. - A 7.0 magnitude earthquake has rocked buildings in Anchorage, the U.S. Geological Survey says.

The quake hit at 9:29 a.m. and was centered seven miles north of Anchorage.

An aftershock with a magnitude of 5.8 struck about five minutes later. 

Shortly after the quake, a tsunami warning was issued for the southern Alaska coastal areas of Cook’s Inlet and part of the Kenai peninsula.

The warning means tsunami waves were expected. 

Officials canceled the tsunami warning at around 11:15 a.m. 

There is no tsunami threat to the California, Oregon and Washington coasts, according to National Weather Service officials. 

It's unclear at this time whether there were injuries.

 

 

Social media posts show damage that included collapsed ceiling tiles at an Anchorage high school and buckled roadway pavement in places.

In a grocery store items can be seen that have fallen off shelves, and ceiling tiles can be seen scattered across a floor.

Alaska averages 40,000 earthquakes per year, with more large quakes than the other 49 states combined.

Southern Alaska has a high risk of earthquakes due to tectonic plates sliding past each other under the region. According to the U.S. Geological Survey, the Pacific plate is sliding northwestward and plunges beneath the North American plate in southern Alaska, the Alaska Peninsula and the Aleutian Islands.

On March 27, 1964, Alaska was hit by a magnitude 9.2 earthquake, the strongest recorded in U.S. history, centered about 75 miles east of Anchorage. The quake, which lasted about 4½ minutes, and the tsunami it triggered claimed about 130 lives.
