On April 4, 2021 at 20:09 UTC, a magnitude 4.2 intermediate depth earthquake struck 105 km ENE of Barishal, Pakistan, at a depth of 74.7 km and coordinates 36.7677°, 75.7308°.
Physical scale: An earthquake of magnitude 4.2 releases seismic energy equivalent to roughly 30 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 476 m — a useful intuition for the size of the slip patch on the fault.
