Pacific 7.4 Earthquake Off Alaska with Tsunami Alert (Updated)

June 24, 2011

UPDATE: Update, 12:31 a.m.: The tsunami warning that was issued for the Alaskan coast has been canceled. No tsunami has been recorded and no danger of one exists for the coastline according to the West Coast and Alaska Tsunami Warning Center.

Reuters reports: A major earthquake of 7.4 magnitude hit in the Pacific Ocean Thursday 107 miles east of Atka, Alaska, at a depth of about 25 miles,and a tsunami warning was in effect for parts of coastal Alaska, warning agencies said.

A second quake of magnitude 7.2 hit in the same vicinity and at the same depth a half-minute later, the U.S. Geological Survey said.

“A Tsunami warning is now in effect which includes the coastal areas of Alaska from Unimak Pass, Alaska (80 miles northeast of Dutch Harbor) to Amchitka Pass, Alaska (125 miles west of Adak),” the West Coast and Alaska Tsunami Warning Center said.

This leaves the coast of the entire Alaska peninsula and all of the Alaska mainland out of harm’s way.

The center monitors tsunami risk only for the west coast of North America from the Mexican border to Alaska.
