7.8 Magnitude Earthquake Hits Alaska Triggering Brief Tsunami Alert

A 7.8 magnitude earthquake struck off the coast of Alaska, triggering a brief tsunami warning for areas 200 miles of the epicentre.

The quake hit 500 miles southwest of Anchorage, and around 60 miles south-southeast of the remote settlement of Perryville, the US Geological Survey said.

“Based on the preliminary earthquake parameters … hazardous tsunami waves are possible for coasts located within 300 km of the earthquake epicenter,” the Pacific Tsunami Warning Center said.




A tsunami warning was in effect for coastal areas of South Alaska and the Alaska Peninsula and Aleutian Islands.

The shallow quake hit at 06:12am GMT. The tsunami warning was cancelled at 8:27am GMT as it no longer posed a threat. However, some areas are expected to see small sea level changes.

The quake was felt hundreds of miles away.



Alaska is part of the seismically active Pacific Ring of Fire.

Alaska was hit by a 9.2-magnitude earthquake in March 1964, the strongest ever recorded in North America. It devastated Anchorage and unleashed a tsunami that slammed the Gulf of Alaska, the US west coast, and Hawaii.

More than 250 people were killed by the quake and the tsunami.
