On May 11, 2023 at 22:07 UTC, a magnitude 4.4 shallow crustal earthquake struck 54 km SSE of Kangding, China, at a depth of 16.0 km and coordinates 29.5306°, 102.1292°.
Physical scale: An earthquake of magnitude 4.4 releases seismic energy equivalent to roughly 60 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 655 m — a useful intuition for the size of the slip patch on the fault.
