M4.7 Earthquake near southern Mid-Atlantic Ridge — December 28, 2024
2024-12-28 01:53:28 UTC (2024-12-28) · approx. 12:53 AM UTC-1 local
On December 28, 2024 at 01:53 UTC, a magnitude 4.7 shallow crustal earthquake struck near southern Mid-Atlantic Ridge, at a depth of 10.0 km and coordinates -13.8578°, -14.6377°. This earthquake was detected by 10 seismic stations with good location accuracy and was assigned a USGS significance rating of 340, placing it among routine seismic activity.
Physical scale: An earthquake of magnitude 4.7 releases seismic energy equivalent to roughly 169 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 1.1 km — a useful intuition for the size of the slip patch on the fault.
