2026-09-19 15:53:54 UTC (4 hours ago) · approx. 9:53 PM UTC+6 local
On September 19, 2026 at 15:53 UTC, a magnitude 4.5 shallow crustal earthquake struck 75 km SE of Kuqa, China, at a depth of 10.0 km and coordinates 41.1968°, 83.5180°. This earthquake was detected by 25 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.
