On January 8, 2025 at 23:39 UTC, a magnitude 4.0 shallow crustal earthquake struck 92 km ENE of Lhasa, China, at a depth of 10.0 km and coordinates 29.9915°, 91.9736°.

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.
