Skwentna, Alaska – A magnitude 4.5 earthquake struck 18 kilometers southeast of Skwentna Friday evening, briefly rattling homes across Southcentral Alaska. The quake, recorded at 55.1 kilometers deep, occurred at 12:03 p.m. local time, according to the U.S. Geological Survey.
Early reports indicate light shaking was felt as far as Anchorage, though no damage or injuries have been reported. According to the USGS, the event registered as intensity level III on the community intensity map, meaning weak to light shaking was likely experienced indoors.
Residents from the Matanuska-Susitna Valley to Anchorage described a short, rolling motion lasting several seconds. Emergency officials have not issued any alerts or tsunami warnings, as the quake’s depth and inland location reduce that risk.
Authorities advise residents to review earthquake preparedness plans, secure heavy items, and keep emergency kits accessible. Aftershocks are possible but not expected to be severe.
The Alaska Earthquake Center continues to monitor seismic activity in the region, noting that moderate quakes are common along the state’s active fault systems. Updates will be provided if additional tremors are detected.
