TREMR

This strong M6.1 earthquake was a shallow-focus event, striking at 16 km beneath Rat Islands, Aleutian Islands, Alaska. Strong earthquakes at this magnitude are widely felt across a broad region and can cause moderate to heavy damage to vulnerable structures near the epicenter.

At 16 km, this is a very shallow earthquake. Shallow-focus events typically generate stronger surface shaking relative to their magnitude, concentrating energy in a smaller area near the epicenter.
