On November 6, 2023 at 05:44 UTC, a magnitude 5.0 shallow crustal earthquake struck near South Indian Ocean, at a depth of 10.0 km and coordinates -34.0720°, 57.8268°. This earthquake was detected by 94 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.
