On April 23, 2023 at 18:10 UTC, a magnitude 4.4 shallow crustal earthquake struck 37 km ESE of Chubek, Tajikistan, at a depth of 9.8 km and coordinates 37.4639°, 70.0889°.
Physical scale: An earthquake of magnitude 4.4 releases seismic energy equivalent to roughly 60 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 655 m — a useful intuition for the size of the slip patch on the fault.
