M5.1 Earthquake near central Mid-Atlantic Ridge — July 8, 2025
2025-07-08 16:48:27 UTC (2025-07-08) · approx. 2:48 PM UTC-2 local
On July 8, 2025 at 16:48 UTC, a magnitude 5.1 shallow crustal earthquake struck near central Mid-Atlantic Ridge, at a depth of 10.0 km and coordinates 3.1408°, -31.3548°. This earthquake was detected by 249 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 400, placing it among routine seismic activity.
Physical scale: An earthquake of magnitude 5.1 releases seismic energy equivalent to roughly 674 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 2.0 km — a useful intuition for the size of the slip patch on the fault.
