On February 12, 2023 at 22:45 UTC, a magnitude 4.0 shallow crustal earthquake struck 73 km NW of Mangan, India, at a depth of 60.9 km and coordinates 27.9860°, 88.0003°.
Physical scale: An earthquake of magnitude 4.0 releases seismic energy equivalent to roughly 15 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 347 m — a useful intuition for the size of the slip patch on the fault.
