On July 26, 2026 at 01:32 UTC, a magnitude 5.1 shallow crustal earthquake struck in the Tristan da Cunha region, at a depth of 10.0 km and coordinates -34.0707°, -14.5430°. This earthquake was detected by 56 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 400, placing it among routine seismic activity.

Physical scale: An earthquake of magnitude 5.1 releases seismic energy equivalent to roughly 674 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 2.0 km — a useful intuition for the size of the slip patch on the fault.
