M5.2 Earthquake near southern Mid-Atlantic Ridge — March 13, 2022
2022-03-13 20:30:11 UTC (2022-03-13) · approx. 7:30 PM UTC-1 local
On March 13, 2022 at 20:30 UTC, a magnitude 5.2 shallow crustal earthquake struck near southern Mid-Atlantic Ridge, at a depth of 10.0 km and coordinates -29.9761°, -13.9333°.
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.
