M5.2 Earthquake near southern Mid-Atlantic Ridge — January 21, 2025
2025-01-21 05:13:36 UTC (2025-01-21) · approx. 4:13 AM UTC-1 local
On January 21, 2025 at 05:13 UTC, a magnitude 5.2 shallow crustal earthquake struck near southern Mid-Atlantic Ridge, at a depth of 10.0 km and coordinates -27.7265°, -13.1569°. This earthquake was detected by 44 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 416, placing it among routine seismic activity.
Physical scale: An earthquake of magnitude 5.2 releases seismic energy equivalent to roughly 951 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 2.3 km — a useful intuition for the size of the slip patch on the fault.
