On February 13, 2024 at 14:30 UTC, a magnitude 5.0 shallow crustal earthquake struck 215 km ENE of Georgetown, Saint Helena, at a depth of 13.2 km and coordinates -7.2056°, -12.5968°. This earthquake was detected by 95 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.
