M5.1 Earthquake in the Mauritius - Reunion region — October 31, 2024
2024-10-31 22:24:42 UTC (2024-10-31) · approx. 2:24 AM UTC+4 local
On October 31, 2024 at 22:24 UTC, a magnitude 5.1 shallow crustal earthquake struck in the Mauritius - Reunion region, at a depth of 10.0 km and coordinates -19.9227°, 66.3786°. This earthquake was detected by 68 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 400, placing it among routine seismic activity.
Physical scale: An earthquake of magnitude 5.1 releases seismic energy equivalent to roughly 674 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 2.0 km — a useful intuition for the size of the slip patch on the fault.
