About this earthquake

On December 24, 2025 at 15:00 UTC, a magnitude M5.7 earthquake occurred near 207 km SW of Merizo Village, Guam. The hypocenter lay relatively close to the surface at around 23 km, increasing how strongly it was felt. Earthquakes of this magnitude can damage poorly built structures.

Why depth matters

Shallow quakes release energy near the surface — shaking is felt more strongly and damage potential is higher.

Official USGS aftershock forecast

Probability of at least one aftershock at or above the specified magnitude during the entire stated time window. This does not predict an individual earthquake.
