On October 22, 2025 at 13:21 UTC, a magnitude 4.1 shallow crustal earthquake struck 83 km SSW of Liupanshui, China, at a depth of 10.0 km and coordinates 25.9177°, 104.4729°.
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.
