2025-01-21 22:37:14 UTC (2025-01-21) · approx. 4:37 AM UTC+6 local
On January 21, 2025 at 22:37 UTC, a magnitude 4.6 shallow crustal earthquake struck near western Xizang, at a depth of 10.0 km and coordinates 35.4979°, 89.5216°. This earthquake was detected by 77 seismic stations with good 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.
