On April 14, 2021 at 16:45 UTC, a magnitude 4.1 shallow crustal earthquake struck 158 km SW of Bamboo Flat, India, at a depth of 10.0 km and coordinates 10.8839°, 91.5252°.

Physical scale: An earthquake of magnitude 4.1 releases seismic energy equivalent to roughly 21 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 406 m — a useful intuition for the size of the slip patch on the fault.
