2025-10-25 18:06:21 UTC (2025-10-25) · approx. 11:06 PM UTC+5 local
On October 25, 2025 at 18:06 UTC, a magnitude 4.5 shallow crustal earthquake struck 108 km ENE of Aksu, China, at a depth of 10.0 km and coordinates 41.5572°, 81.4829°. This earthquake was detected by 78 seismic stations with excellent 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.
