M4.7 Earthquake near Mid-Indian Ridge — March 22, 2021
2021-03-22 07:26:47 UTC (2021-03-22) · approx. 12:26 PM UTC+5 local
On March 22, 2021 at 07:26 UTC, a magnitude 4.7 shallow crustal earthquake struck near Mid-Indian Ridge, at a depth of 10.0 km and coordinates -22.8100°, 69.1675°.
Physical scale: An earthquake of magnitude 4.7 releases seismic energy equivalent to roughly 169 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 1.1 km — a useful intuition for the size of the slip patch on the fault.
