2021-11-30 21:39:35 UTC (2021-11-30) · approx. 4:39 AM UTC+7 local
On November 30, 2021 at 21:39 UTC, a magnitude 4.7 shallow crustal earthquake struck 26 km ESE of Xunchang, China, at a depth of 10.0 km and coordinates 28.3910°, 104.9714°.
Physical scale: An earthquake of magnitude 4.7 releases seismic energy equivalent to roughly 169 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 1.1 km — a useful intuition for the size of the slip patch on the fault.
