Another large earthquake has hit the North Slope region just hours after being rattled Sunday morning, according to the U.S. Geological Survey. 

At 1:15 p.m., a 6.0 aftershock shook 43 miles southwest of Katktovik. The earthquake came several hours after the North Slope was struck by the most powerful earthquake ever recorded in the region, according to the state's seismologist.

 

The USGS says the initial 6.4 quake struck at 6:58 a.m. near the Beaufort Sea coast. 

It hit an area 41.8 miles east of Kavik River Camp and 342.9 miles northeast of Fairbanks. The Alaska Earthquake Center says people have reported feeling the quake from Kaktovik and Deadhorse and as far south as Fairbanks.

The survey says the earthquake has a depth of about four-tenths of a mile.

In January, a powerful undersea earthquake sent Alaskans fumbling for suitcases and racing to evacuation centers in the middle of the night after a cellphone alert warned a tsunami could hit communities along the state's southern coast and parts of British Columbia. The magnitude 7.9 quake in the Gulf of Alaska triggered the alert.
