A small earthquake of magnitude 2.1 was recorded early Tuesday southwest of Iliamna Volcano on the Alaska Peninsula, according to data from the Alaska Earthquake Center.
The seismic event occurred at 4:01 a.m. Alaska Standard Time at a depth of about 86 miles (139 km) below the surface, indicating it originated deep within the Earth’s crust. The quake’s location was roughly 8 miles southwest of Iliamna Volcano, a well-monitored volcanic and seismic area in southwest Alaska.
At this level of magnitude, such earthquakes are typically too weak to cause damage and often go unnoticed by residents in nearby communities. Deep-focus earthquakes like this one are common in Alaska due to the region’s complex tectonic setting, where the Pacific Plate subducts beneath the North American Plate.

The Alaska Earthquake Center continues to monitor seismic activity statewide through its network of sensors and provides real-time updates to the public and emergency management officials. Alaska is one of the most seismically active regions in the United States and experiences thousands of earthquakes each year, most of them small and non-damaging.
