On January 19, 2022 at 21:52 UTC, a magnitude 4.5 shallow crustal earthquake struck 55 km WSW of Guangyuan, China, at a depth of 10.0 km and coordinates 32.2752°, 105.2718°.
Physical scale: An earthquake of magnitude 4.5 releases seismic energy equivalent to roughly 85 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 767 m — a useful intuition for the size of the slip patch on the fault.
