Big Lake, Alaska – A light earthquake rippled through Southcentral Alaska on Saturday morning, briefly shaking communities near Big Lake and the greater Anchorage area. The tremor was strong enough to be noticed by some residents but caused no immediate reports of damage or injuries.
According to the U.S. Geological Survey, the earthquake registered a magnitude of 3.5 and struck about 1 kilometer south-southwest of Big Lake at a depth of roughly 20 kilometers. The event occurred Saturday afternoon local time, placing it well within the range of quakes that are commonly felt but rarely cause structural impacts in this part of Alaska.
Residents in Big Lake, Wasilla, and parts of Anchorage may have noticed a quick jolt or light rolling motion, especially in upper floors of buildings. Alaska sits along one of the most seismically active regions in the world, and small earthquakes like this are frequent reminders of that underlying activity. Local emergency management agencies did not issue any advisories following the quake.
Officials encourage residents to review basic earthquake safety, including securing heavy furniture and knowing safe spots to drop, cover, and hold on if stronger shaking occurs. The USGS continues to monitor seismic activity in the region, and additional updates will be issued if aftershocks or new activity develop later this weekend.
