On January 27, 2023 at 19:06 UTC, a magnitude 4.5 shallow crustal earthquake struck 105 km W of Kashgar, China, at a depth of 39.4 km and coordinates 39.6189°, 74.7829°. This earthquake was detected by 58 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 312, placing it among routine seismic activity.
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.
