2024-01-22 23:55:34 UTC (2024-01-22) · approx. 4:55 AM UTC+5 local
On January 22, 2024 at 23:55 UTC, a magnitude 4.5 shallow crustal earthquake struck 131 km W of Aykol, China, at a depth of 9.2 km and coordinates 41.1675°, 78.5915°. This earthquake was detected by 85 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.
