Early morning aftershocks shook Seward on Thursday.
Shaking started with a 4.9 tremor at 5:21 a.m. just eight miles northwest of Anchorage and 22 miles deep. It was preceded and followed by other, smaller quakes. A magnitude 3.3 earthquake at 7:38 a.m. registered 36 miles southwest of Seward, but has not been reviewed by a seismologist yet.
The 4.9 magnitude tremor, an aftershock from the 7.0 earthquake that shook Seward on Nov. 30, was the largest aftershock felt since early December.
Over 6,100 aftershocks have been recorded according to the University of Alaska Fairbanks Earthquake Center. In comparison, in Dec. 2017, Alaska recorded less than 3000 quakes throughout the entire state. The statewide total for 2018 is at 51,612 quakes.
The last large aftershock was a 4.8 quake on Dec. 9.
