M5.1 Earthquake near northern Mid-Atlantic Ridge — February 4, 2025
2025-02-04 18:21:57 UTC (2025-02-04) · approx. 3:21 PM UTC-3 local
On February 4, 2025 at 18:21 UTC, a magnitude 5.1 shallow crustal earthquake struck near northern Mid-Atlantic Ridge, at a depth of 10.0 km and coordinates 30.9335°, -41.2503°. This earthquake was detected by 92 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.
