M4.7 Earthquake near South Atlantic Ocean — June 12, 2025
2025-06-12 22:23:36 UTC (2025-06-12) · approx. 10:23 PM UTC+0 local
On June 12, 2025 at 22:23 UTC, a magnitude 4.7 shallow crustal earthquake struck near South Atlantic Ocean, at a depth of 10.0 km and coordinates -2.9423°, 0.0956°. This earthquake was detected by 33 seismic stations with excellent 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.
