On December 27, 2022 at 19:38 UTC, a magnitude 4.0 shallow crustal earthquake struck 55 km N of Chitre, Nepal, at a depth of 24.6 km and coordinates 28.9260°, 83.6137°.

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.
