TREMR

This moderate M5.4 earthquake was a shallow-focus event, striking at 17 km beneath Severo-Kuril’sk, Russia. Moderate earthquakes are widely felt and can cause light damage near the epicenter, particularly to older or unreinforced structures.

At 17 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.
