On January 4, 2021 at 02:58 UTC, a magnitude 5.0 shallow crustal earthquake struck 4 km N of Luocheng, China, at a depth of 10.0 km and coordinates 29.4293°, 104.0285°.
Physical scale: An earthquake of magnitude 5.0 releases seismic energy equivalent to roughly 477 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 1.7 km — a useful intuition for the size of the slip patch on the fault.
