On March 27, 2021 at 17:24 UTC, a magnitude 4.5 shallow crustal earthquake struck near western Xizang, at a depth of 51.7 km and coordinates 35.5062°, 89.4991°.

Physical scale: An earthquake of magnitude 4.5 releases seismic energy equivalent to roughly 85 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 767 m — a useful intuition for the size of the slip patch on the fault.
