On April 14, 2023 at 18:32 UTC, a magnitude 4.2 shallow crustal earthquake struck 52 km SSE of Kangding, China, at a depth of 10.0 km and coordinates 29.5877°, 102.2282°.
Physical scale: An earthquake of magnitude 4.2 releases seismic energy equivalent to roughly 30 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 476 m — a useful intuition for the size of the slip patch on the fault.
