M5.3 Earthquake near southern Mid-Atlantic Ridge — September 25, 2024
2024-09-25 14:01:05 UTC (2024-09-25) · approx. 2:01 PM UTC+0 local
On September 25, 2024 at 14:01 UTC, a magnitude 5.3 shallow crustal earthquake struck near southern Mid-Atlantic Ridge, at a depth of 10.0 km and coordinates -57.6266°, -6.9134°. This earthquake was detected by 71 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 432, placing it among routine seismic activity.
Physical scale: An earthquake of magnitude 5.3 releases seismic energy equivalent to roughly 1 kilotons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 2.7 km — a useful intuition for the size of the slip patch on the fault.
