2022-03-28 21:22:33 UTC (2022-03-28) · approx. 3:22 AM UTC+6 local
On March 28, 2022 at 21:22 UTC, a magnitude 4.7 shallow crustal earthquake struck in the Andaman Islands, India region, at a depth of 10.0 km and coordinates 14.6269°, 93.0229°.
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.
