2026-10-22 15:45:37 UTC (1 hour ago) · approx. 9:45 PM UTC+6 local
On October 22, 2026 at 15:45 UTC, a magnitude 4.9 shallow crustal earthquake struck near western Xizang, at a depth of 10.0 km and coordinates 33.7966°, 86.2316°. This earthquake was detected by 49 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 369, placing it among routine seismic activity.
Physical scale: An earthquake of magnitude 4.9 releases seismic energy equivalent to roughly 338 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 1.4 km — a useful intuition for the size of the slip patch on the fault.
