2021-11-16 08:33:01 UTC (2021-11-16) · approx. 2:33 PM UTC+6 local
On November 16, 2021 at 08:33 UTC, a magnitude 5.3 shallow crustal earthquake struck near South Indian Ocean, at a depth of 10.0 km and coordinates -8.9532°, 88.1480°.
Physical scale: An earthquake of magnitude 5.3 releases seismic energy equivalent to roughly 1 kilotons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 2.7 km — a useful intuition for the size of the slip patch on the fault.
