A magnitude 4.9 earthquake was recorded by the U.S. Geological Survey (USGS) at 11:57 UTC on Oct. 16, 2026. The agency placed the epicenter in open water, 119 kilometers southwest of Merizo Village, Guam, at a depth of 10 kilometers.

The epicenter was in open water well south of Guam, with no village close enough to be directly affected.
