M4.9 Earthquake near North Atlantic Ocean — May 25, 2025
2025-05-25 04:11:25 UTC (2025-05-25) · approx. 12:11 AM UTC-4 local
On May 25, 2025 at 04:11 UTC, a magnitude 4.9 shallow crustal earthquake struck near North Atlantic Ocean, at a depth of 10.0 km and coordinates 15.9807°, -55.7288°. This earthquake was detected by 61 seismic stations with good location accuracy and was assigned a USGS significance rating of 369, placing it among routine seismic activity.
Physical scale: An earthquake of magnitude 4.9 releases seismic energy equivalent to roughly 338 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 1.4 km — a useful intuition for the size of the slip patch on the fault.
