M4.7 Earthquake south of Africa — June 28, 2026
2026-06-28 08:34:26 UTC (2026-06-28) · approx. 10:34 AM UTC+2 local
On June 28, 2026 at 08:34 UTC, a magnitude 4.7 shallow crustal earthquake struck south of Africa, at a depth of 10.0 km and coordinates -52.7498°, 27.4601°. This earthquake was detected by 20 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.
