On July 27, 2026 at 04:31 UTC, a magnitude 4.1 shallow crustal earthquake struck near western Xizang, at a depth of 10.0 km and coordinates 35.4017°, 87.6776°.

Physical scale: An earthquake of magnitude 4.1 releases seismic energy equivalent to roughly 21 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 406 m — a useful intuition for the size of the slip patch on the fault.
