On October 24, 2023 at 18:02 UTC, a magnitude 4.6 shallow crustal earthquake struck near western Xizang, at a depth of 12.3 km and coordinates 33.5193°, 87.4234°. This earthquake was detected by 127 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 326, placing it among routine seismic activity.

Physical scale: An earthquake of magnitude 4.6 releases seismic energy equivalent to roughly 120 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 899 m — a useful intuition for the size of the slip patch on the fault.
