Dataset at a glance — Puerto Rico

Over the past 30 days, Puerto Rico has recorded 142 earthquakes of magnitude 2.5 or greater in our tracker. 1 reached magnitude 5.0 or higher. 5 landed between M4.0 and M4.9. The remaining 136 fell in the M2.5–M3.9 band. By depth: 124 shallow (<70 km), 18 intermediate (70–300 km). 88 of the epicenters were offshore. 13 events produced at least one felt report, totalling 139 citizen submissions to the USGS Did You Feel It? system. Cluster detection flagged 1 aftershock sequence; the largest contained 13 smaller events within 20 km and 72 hours of its mainshock. Focal depths ranged from 4.2 km to 158.0 km. All 142 solutions have been reviewed by a USGS seismologist.

Leading the list is a magnitude 5.0 event near 51 km S of Boca de Yuma, Dominican Republic at 82.0 km depth, which drew 125 felt reports from the public. The second-ranked event, at magnitude 4.1 near 34 km E of Miches, Dominican Republic, trails by 0.9 magnitude units — a meaningful gap that makes the leader clearly dominant in energy release. Rounding out the top three is a magnitude 4.1 earthquake near 144 km NNE of Cruz Bay, U.S. Virgin Islands.
