An earthquake with a reviewed magnitude of 5.3 rumbled through Southcentral Alaska on Saturday morning.
The 9:59 a.m. quake, centered 8 miles northwest of Anchorage, occurred at a depth of about 26 miles, according to the Alaska Earthquake Center. Shaking was felt widely across the region, with Alaskans on social media describing a loud rumbling, rattling household items and questions in the moment about how long the temblor would last.
Saturday’s earthquake was an aftershock of the magnitude 7.1 earthquake in November 2018 that caused widespread damage throughout Anchorage and the Matanuska-Susitna region, the Alaska Earthquake Center said.
We, in cooperation with @UAA Engineering Dept, just installed 5 new strong motion stations in Eagle River & Mat-Su last week, to provide additional info on ground motions in this region. Today's M5.3 aftershock is the largest since a M5.1 on Nov 7, 2020. 2/2

A tsunami was not expected, according to the U.S. National Tsunami Warning Center. The Alaska Department of Transportation and Public Facilities on Saturday morning said on Twitter that the agency didn’t have any reports of damage at that time but would perform “visual inspections of our bridge structures within the quake zone.”
That was quite a shaker. We do not have any reports of damage at this time, however, DOT&PF Maintenance & Operations is performing visual inspections of our bridge structures within the quake zone. We'll post updates if needed. Thanks and stay safe!
