On November 21, 2020 at 21:49 UTC, a magnitude 4.5 shallow crustal earthquake struck 128 km NW of Rikaze, China, at a depth of 10.0 km and coordinates 30.1884°, 88.1002°.
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.
