This moderate M5.1 earthquake was a deep-focus event, striking at 428 km beneath northwest of the Kuril Islands. Moderate earthquakes are widely felt and can cause light damage near the epicenter, particularly to older or unreinforced structures.

At 428 km, this is a deep-focus earthquake. Deep events release enormous energy but produce weaker surface shaking than shallow earthquakes of similar magnitude, often felt over vast distances with less localized damage.
