2023-12-02 22:37:34 UTC (2023-12-02) · approx. 3:37 AM UTC+5 local
On December 2, 2023 at 22:37 UTC, a magnitude 4.0 intermediate depth earthquake struck 41 km SSW of Khorugh, Tajikistan, at a depth of 126.5 km and coordinates 37.1609°, 71.3331°.
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.
