M5.0 Earthquake in the Bouvet Island region — August 5, 2025
2025-08-05 03:49:25 UTC (2025-08-05) · approx. 3:49 AM UTC+0 local
On August 5, 2025 at 03:49 UTC, a magnitude 5.0 shallow crustal earthquake struck in the Bouvet Island region, at a depth of 10.0 km and coordinates -54.3952°, 5.4974°. This earthquake was detected by 33 seismic stations with good location accuracy and was assigned a USGS significance rating of 385, placing it among routine seismic activity.
Physical scale: An earthquake of magnitude 5.0 releases seismic energy equivalent to roughly 477 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 1.7 km — a useful intuition for the size of the slip patch on the fault.
