An earthquake with a reviewed magnitude of 3.5 occurred Saturday afternoon, shaking parts of Southcentral Alaska.
The earthquake, centered about 18 miles north of Anchorage, hit at 2:26 p.m. at a depth of 25.1 miles, according to the Alaska Earthquake Center. Shaking was reportedly felt from the Mat-Su area to Anchorage, according to a shakemap of user reports.
Saturday’s quake was located in the same rupture patch as the 7.1 earthquake that shook the region on Nov. 30, 2018, which would make it an aftershock. The Alaska Earthquake Center expects aftershocks from the November 2018 earthquake to last about 2 1/2 years, or until around June 2021.

“People in Southcentral should expect to feel more aftershocks, but only infrequently. Right now, we’re seeing about half a dozen Anchorage aftershocks per day, and most are far too small to feel,” the center wrote on its website in September.
