Washington (Web Desk): An 8.2 magnitude strong earthquake struck off the Alaskan peninsula late Wednesday, generating small waves but no major tsunami, a foreign news agency reported.
According to the United States Geological Survey (USGS), the earthquake hit 56 miles (91 kilometers) southeast of the town of Perryville. The quake struck at 10:15 pm Wednesday (0615 GMT Thursday).
The US government´s National Tsunami Warning Center (NTWC) immediately issued a tsunami alert for south Alaska and the Alaskan peninsula.
It initially warned of hazardous waves over the next three hours.
But after nearly three hours the maximum height detected by the center was eight inches (21 centimeters) and it downgraded the tsunami threat alerts to advisories.
Tsunami warning sirens had been broadcast across Kodiak, an island with a population of about 6,000 people, along Alaska´s coastline.
Small waves hit the coast of Kodiak, according to a broadcaster on local radio station KMXT. She said authorities had lifted evacuation orders, with no reports of any damage.
Alaska is part of the seismically active Pacific Ring of Fire. It 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.
In October, a 7.5 magnitude earthquake also caused tsunami waves in Alaska´s southern coast but no casualties were reported.
