On November 11, 2022 at 23:13 UTC, a magnitude 4.6 shallow crustal earthquake struck 87 km WSW of Zhaotong, China, at a depth of 18.2 km and coordinates 27.0650°, 102.8840°. This earthquake was detected by 67 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.
