On June 4, 2021 at 22:12 UTC, a magnitude 4.1 shallow crustal earthquake struck 6 km NNW of Dali, China, at a depth of 10.0 km and coordinates 25.6398°, 100.1814°.
Physical scale: An earthquake of magnitude 4.1 releases seismic energy equivalent to roughly 21 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 406 m — a useful intuition for the size of the slip patch on the fault.
