On February 22, 2023 at 08:00 UTC, a magnitude 4.8 shallow crustal earthquake struck 70 km WNW of Jumla, Nepal, at a depth of 20.9 km and coordinates 29.6254°, 81.5737°. This earthquake was detected by 77 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 356, placing it among routine seismic activity.

Physical scale: An earthquake of magnitude 4.8 releases seismic energy equivalent to roughly 239 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 1.2 km — a useful intuition for the size of the slip patch on the fault.
