On August 27, 2024 at 15:51 UTC, a magnitude 4.6 shallow crustal earthquake struck 40 km SE of Bandrélé, Mayotte, at a depth of 12.5 km and coordinates -13.1364°, 45.4937°. This earthquake was detected by 50 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 327, 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.
