2026-06-30 10:32:27 UTC (2026-06-30) · approx. 3:32 PM UTC+5 local
On June 30, 2026 at 10:32 UTC, a magnitude 4.0 shallow crustal earthquake struck 121 km W of Kashgar, China, at a depth of 19.2 km and coordinates 39.6143°, 74.5888°.
Physical scale: An earthquake of magnitude 4.0 releases seismic energy equivalent to roughly 15 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 347 m — a useful intuition for the size of the slip patch on the fault.
