2026-03-23 22:44:01 UTC (2026-03-23) · approx. 3:44 AM UTC+5 local
On March 23, 2026 at 22:44 UTC, a magnitude 4.3 shallow crustal earthquake struck near Mid-Indian Ridge, at a depth of 10.0 km and coordinates -21.6616°, 69.0735°.
Physical scale: An earthquake of magnitude 4.3 releases seismic energy equivalent to roughly 43 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 558 m — a useful intuition for the size of the slip patch on the fault.
