2021-03-27 03:37:44 UTC (2021-03-27) · approx. 8:37 AM UTC+5 local
On March 27, 2021 at 03:37 UTC, a magnitude 4.6 shallow crustal earthquake struck near Indian Ocean Triple Junction, at a depth of 10.0 km and coordinates -26.5752°, 67.7071°.
Physical scale: An earthquake of magnitude 4.6 releases seismic energy equivalent to roughly 120 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 899 m — a useful intuition for the size of the slip patch on the fault.
