On January 23, 2024 at 19:20 UTC, a magnitude 4.1 shallow crustal earthquake struck 115 km WNW of Aykol, China, at a depth of 10.0 km and coordinates 41.3980°, 78.8923°.
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.
