M5.0 Earthquake near northern Mid-Atlantic Ridge — May 24, 2021
2021-05-24 01:01:26 UTC (2021-05-24) · approx. 10:01 PM UTC-3 local
On May 24, 2021 at 01:01 UTC, a magnitude 5.0 shallow crustal earthquake struck near northern Mid-Atlantic Ridge, at a depth of 10.0 km and coordinates 28.2083°, -43.8757°.
Physical scale: An earthquake of magnitude 5.0 releases seismic energy equivalent to roughly 477 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 1.7 km — a useful intuition for the size of the slip patch on the fault.
