On June 12, 2021 at 18:31 UTC, a magnitude 3.9 shallow crustal earthquake struck 17 km WNW of T?lcher, India, at a depth of 10.0 km and coordinates 21.0204°, 85.0848°.
Physical scale: An earthquake of magnitude 3.9 releases seismic energy equivalent to roughly 11 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 296 m — a useful intuition for the size of the slip patch on the fault.
