2026-08-28 22:07:32 UTC (2026-08-28) · approx. 3:07 AM UTC+5 local
On August 28, 2026 at 22:07 UTC, a magnitude 4.9 shallow crustal earthquake struck 120 km NNE of Aksu, China, at a depth of 10.0 km and coordinates 42.2447°, 80.5748°. This earthquake was detected by 68 seismic stations with good location accuracy and was assigned a USGS significance rating of 369, 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.
