Shallow M5.7 earthquake hits southwest of Guam

A shallow M5.7 earthquake was recorded at 15:00 UTC on December 24, 2025, approximately 218 km (135 miles) southwest of Merizo Village, Guam. The earthquake struck at a depth of 10.0 km (6.2 miles), according to USGS data.

The epicenter was located at coordinates 143.4°E, 11.8°N, offshore and southwest of the island of Guam. This area is part of the western Pacific Ocean, with the nearest population centers including Merizo Village on Guam.

Given its offshore location southwest of Guam, the region is remote from major infrastructure, but maritime routes and undersea communication cables could be present in this part of the Pacific Ocean.

There is no tsunami threat associated with this earthquake, based on its location and available data.

The maximum estimated intensity for this event was III, and the significance index is 500 (on a scale that runs through 1 000), based on magnitude and estimated impact.

This region lies near the boundary of the Pacific and Philippine Sea tectonic plates, an area recognized for seismic activity due to subduction processes and plate movements in the western Pacific.
