Over the past 30 days, Puerto Rico has recorded 159 earthquakes of magnitude 2.5 or greater in our tracker. 5 landed between M4.0 and M4.9. The remaining 154 fell in the M2.5–M3.9 band. By depth: 144 shallow (<70 km), 15 intermediate (70–300 km). 78 of the epicenters were offshore. 4 events produced at least one felt report, totalling 6 citizen submissions to the USGS Did You Feel It? system. Cluster detection flagged 3 aftershock sequences; the largest contained 6 smaller events within 20 km and 72 hours of its mainshock. Focal depths ranged from 4.9 km to 157.0 km. All 159 solutions have been reviewed by a USGS seismologist.
Leading the list is a magnitude 4.2 event near 88 km N of Culebra, Puerto Rico at 26.0 km depth. The second-ranked event, at magnitude 4.1 near 93 km NE of Cruz Bay, U.S. Virgin Islands, trails by 0.1 magnitude units — a narrow gap, indicating two comparably energetic events in the current window. Rounding out the top three is a magnitude 4.1 earthquake near 33 km NE of Otra Banda, Dominican Republic.
