On June 18, 2026 at 23:00 UTC, a magnitude 4.2 intermediate depth earthquake struck 66 km E of Khorugh, Tajikistan, at a depth of 190.6 km and coordinates 37.5881°, 72.2944°.
Physical scale: An earthquake of magnitude 4.2 releases seismic energy equivalent to roughly 30 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 476 m — a useful intuition for the size of the slip patch on the fault.
