M4.5 Earthquake near South Indian Ocean — November 6, 2023
2023-11-06 18:05:36 UTC (2023-11-06) · approx. 10:05 PM UTC+4 local
On November 6, 2023 at 18:05 UTC, a magnitude 4.5 shallow crustal earthquake struck near South Indian Ocean, at a depth of 10.0 km and coordinates -34.0075°, 57.9118°. This earthquake was detected by 40 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 312, placing it among routine seismic activity.
Physical scale: An earthquake of magnitude 4.5 releases seismic energy equivalent to roughly 85 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 767 m — a useful intuition for the size of the slip patch on the fault.
