On April 27, 2026 at 22:58 UTC, a magnitude 4.0 shallow crustal earthquake struck 84 km ESE of Kuqa, China, at a depth of 10.0 km and coordinates 41.5187°, 83.9151°.
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.
