2024-10-21 22:40:03 UTC (2024-10-21) · approx. 4:40 AM UTC+6 local
On October 21, 2024 at 22:40 UTC, a magnitude 4.1 shallow crustal earthquake struck 147 km SE of Kuqa, China, at a depth of 10.0 km and coordinates 40.7324°, 84.1160°.
Physical scale: An earthquake of magnitude 4.1 releases seismic energy equivalent to roughly 21 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 406 m — a useful intuition for the size of the slip patch on the fault.
