On January 22, 2024 at 23:44 UTC, a magnitude 4.2 shallow crustal earthquake struck 130 km WNW of Aykol, China, at a depth of 5.9 km and coordinates 41.2605°, 78.6373°.

Physical scale: An earthquake of magnitude 4.2 releases seismic energy equivalent to roughly 30 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 476 m — a useful intuition for the size of the slip patch on the fault.
