On May 30, 2025 at 05:36 UTC, a magnitude 6.2 shallow crustal earthquake struck southwest of Africa, at a depth of 10.0 km and coordinates -53.2836°, 9.1051°. The USGS PAGER system issued a green alert level for this event, indicating no significant casualties or damage expected. This earthquake was detected by 60 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 591, placing it among routine seismic activity.
Physical scale: An earthquake of magnitude 6.2 releases seismic energy equivalent to roughly 30 kilotons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 11 km — a useful intuition for the size of the slip patch on the fault.
