On July 14, 2021 at 15:36 UTC, a magnitude 5.0 shallow crustal earthquake struck 43 km W of Tianpeng, China, at a depth of 10.0 km and coordinates 30.9335°, 103.4915°.

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.
