Skwentna, AK – A small but notable earthquake was recorded in central Alaska early Thursday, shaking an area west-northwest of Anchorage, according to seismic officials.
According to the Alaska Earthquake Center, the earthquake measured magnitude 3.3 and struck approximately 34 kilometers (21 miles) west-northwest of Skwentna at 8:05 a.m. Alaska Standard Time Thursday. The quake occurred at a depth of about 109.5 kilometers, classifying it as a deep earthquake.
Because of its depth, the tremor was less likely to be felt at the surface. As of Thursday morning, no felt reports had been submitted by residents, and Note: there were no immediate reports of damage, injuries, or service disruptions.
Skwentna is located in the Matanuska-Susitna Borough, roughly 70 miles northwest of Anchorage, a region that frequently experiences seismic activity due to Alaska’s position along the Pacific Ring of Fire. Alaska averages tens of thousands of earthquakes each year, though most are small and go unnoticed.
Seismologists note that deeper earthquakes, like this one, tend to dissipate energy before reaching the surface, reducing the risk of structural damage. Officials continue to monitor the region for any aftershocks, though none were immediately reported.
Residents who felt shaking are encouraged to submit reports through the Alaska Earthquake Center’s “Did You Feel It?” program, which helps scientists better understand how earthquakes are experienced across different communities.
While Thursday’s quake was considered minor, experts remind Alaskans to remain prepared, review earthquake safety plans, and secure heavy household items, especially in seismically active areas.
