"A shallow 8.2 magnitude earthquake struck off the Alaskan peninsula late Wednesday, the United States Geological Survey said, prompting a tsunami warning. The earthquake hit 56 miles (91 kilometers) southeast of the town of Perryville, the USGS said, with a tsunami warning in effect for south Alaska and the Alaskan peninsula. The US government issued a tsunami warning for Alaska's southeast.

"Hazardous tsunami waves for this earthquake are possible within the next three hours along some coasts," the US Tsunami Warning System said in a statement. Perryville is a small village about 500 miles from Anchorage, Alaska's biggest city."
