TREMR

This strong M6.3 earthquake was a shallow-focus event, striking at 12 km beneath Hihifo, Tonga. 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 12 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.
