On September 9, 2026 at 17:03 UTC, a magnitude 4.0 shallow crustal earthquake struck 28 km SE of Chayek, Kyrgyzstan, at a depth of 12.1 km and coordinates 41.7682°, 74.7934°.
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.
