On July 27, 2026 at 22:32 UTC, a magnitude 5.0 shallow crustal earthquake struck 112 km ENE of Georgetown, Saint Helena, at a depth of 10.0 km and coordinates -7.5058°, -13.4844°. This earthquake was detected by 64 seismic stations with excellent 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.
