On October 16, 2024 at 22:23 UTC, a magnitude 4.9 shallow crustal earthquake struck 138 km W of Aykol, China, at a depth of 10.0 km and coordinates 41.1512°, 78.5080°. This earthquake was detected by 193 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 370, placing it among routine seismic activity.

Physical scale: An earthquake of magnitude 4.9 releases seismic energy equivalent to roughly 338 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 1.4 km — a useful intuition for the size of the slip patch on the fault.
