Forecasters today ruled out the possibility of a tsunami along the Southern California coastline, about four hours after an 8.2-magnitude earthquake struck off the coast of Alaska.

The all-clear was posted on the National Weather Service’s Twitter page about 3 a.m. Pacific Time with a caveat: “No tsunami threat for So Cal. Stronger than normal currents are possible in the harbors and bays later this morning.”

The quake struck at 11:15 p.m. PT on Wednesday about 50 miles southeast of Perryville on the Alaskan Peninsula at a shallow depth of 29miles, according to the U.S. Geological Survey and Alaska Earthquake Center.

The earthquake was felt throughout the Alaska Peninsula and Kodiak, the Alaska Earthquake Center said.

The event prompted the NWS to evaluate the possibility of tsunamis along the West Coast, including Los Angeles, Orange County and San DiegoCounty.
