2021-08-08 22:54:14 UTC (2021-08-08) · approx. 4:54 AM UTC+6 local
On August 8, 2021 at 22:54 UTC, a magnitude 4.5 shallow crustal earthquake struck 116 km SE of Kuqa, China, at a depth of 8.1 km and coordinates 40.9263°, 83.8402°.
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.
