King Cove, Alaska – A light offshore earthquake struck south of the Alaska Peninsula early Monday, with a magnitude 3.3 tremor recorded at 5:28 a.m. local time, too weak to cause damage but notable across the Aleutian region.
According to the U.S. Geological Survey, the quake hit 98 kilometers south of King Cove at a depth of 35 kilometers, a level that often reduces surface shaking. The event was reviewed and confirmed within minutes, with no immediate reports of injuries or infrastructure disruption.
Communities including Cold Bay, Sand Point, and Unalaska sit within the broader seismic zone, though shaking at that distance likely registered as faint or not felt at all. The Aleutians remain one of the most seismically active regions in North America, where frequent low-magnitude quakes occur along the Pacific Plate boundary.
No tsunami threat was issued, and critical infrastructure such as regional airstrips and ferry routes remained fully operational through the morning hours. Residents are still encouraged to secure loose items and review emergency plans, especially in coastal zones where stronger quakes can develop with little warning.
Seismic monitoring continues across southern Alaska, with additional updates expected if activity increases through Monday.
