M4.9 Earthquake near South Indian Ocean — October 3, 2024
2024-10-03 17:39:44 UTC (2024-10-03) · approx. 8:39 PM UTC+3 local
On October 3, 2024 at 17:39 UTC, a magnitude 4.9 shallow crustal earthquake struck near South Indian Ocean, at a depth of 10.0 km and coordinates -37.2493°, 52.1603°. This earthquake was detected by 71 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 369, placing it among routine seismic activity.
Physical scale: An earthquake of magnitude 4.9 releases seismic energy equivalent to roughly 338 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 1.4 km — a useful intuition for the size of the slip patch on the fault.
