M5.3 Earthquake near Southwest Indian Ridge — April 13, 2022
2022-04-13 19:13:01 UTC (2022-04-13) · approx. 11:13 PM UTC+4 local
On April 13, 2022 at 19:13 UTC, a magnitude 5.3 shallow crustal earthquake struck near Southwest Indian Ridge, at a depth of 10.0 km and coordinates -27.7678°, 63.9486°.
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.
