On February 1, 2022 at 23:13 UTC, a magnitude 4.6 shallow crustal earthquake struck near Southern Qinghai, China, at a depth of 10.0 km and coordinates 33.3086°, 95.0293°.
Physical scale: An earthquake of magnitude 4.6 releases seismic energy equivalent to roughly 120 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 899 m — a useful intuition for the size of the slip patch on the fault.
