2024-01-22 21:38:36 UTC (2024-01-22) · approx. 2:38 AM UTC+5 local
On January 22, 2024 at 21:38 UTC, a magnitude 4.5 shallow crustal earthquake struck 113 km WNW of Aykol, China, at a depth of 10.0 km and coordinates 41.3296°, 78.8771°. This earthquake was detected by 47 seismic stations with good location accuracy and was assigned a USGS significance rating of 312, placing it among routine seismic activity.
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.
