M3.7 Earthquake 5 km SW of Tallaboa, Puerto Rico — June 3, 2025
2025-06-03 22:24:54 UTC (2025-06-03) · approx. 6:24 PM UTC-4 local
Felt by 15 people across nearby locations.
On June 3, 2025 at 22:24 UTC, a magnitude 3.7 shallow crustal earthquake struck 5 km SW of Tallaboa, Puerto Rico, at a depth of 8.0 km and coordinates 17.9613°, -66.7490°. The earthquake was reported felt by 15 peopleacross nearby locations, with a maximum shaking intensity of Modified Mercalli Intensity (MMI) 3.4 (light). This earthquake was detected by 25 seismic stations with good location accuracy and was assigned a USGS significance rating of 218, placing it among routine seismic activity.
Physical scale: An earthquake of magnitude 3.7 releases seismic energy equivalent to roughly 5.5 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 219 m — a useful intuition for the size of the slip patch on the fault.
The epicenter is located in Puerto Rico, a region characterized by the Puerto Rico Trench oblique subduction zone and the Muertos Trough, with complex Caribbean–North American plate interactions. The nearest mapped fault system is the Puerto Rico Trench. View all earthquakes in Puerto Rico.

Were there aftershocks?
Aftershock activity is monitored continuously by the USGS. Aftershock sequences from magnitude 3.7 earthquakes can continue for several days and gradually diminish over time.
Has Puerto Rico had earthquakes this big before?
The largest recorded earthquake in Puerto Rico was the M7.3 offshore earthquake of October 11, 1918. Today's magnitude 3.7 event is significantly smaller than that historical record.
