On July 31, 2024 at 17:33 UTC, a magnitude 4.6 shallow crustal earthquake struck 185 km ENE of Port Mathurin, Mauritius, at a depth of 10.0 km and coordinates -19.3347°, 65.1480°. This earthquake was detected by 12 seismic stations with good location accuracy and was assigned a USGS significance rating of 326, placing it among routine seismic activity.
Physical scale: An earthquake of magnitude 4.6 releases seismic energy equivalent to roughly 120 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 899 m — a useful intuition for the size of the slip patch on the fault.
