On February 28, 2023 at 14:46 UTC, a magnitude 5.2 shallow crustal earthquake struck 42 km S of Kangding, China, at a depth of 10.0 km and coordinates 29.6162°, 101.9744°. This earthquake was detected by 98 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 418, placing it among routine seismic activity.

Physical scale: An earthquake of magnitude 5.2 releases seismic energy equivalent to roughly 951 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 2.3 km — a useful intuition for the size of the slip patch on the fault.
