On December 14, 2021 at 22:17 UTC, a magnitude 4.8 shallow crustal earthquake struck 22 km ESE of Chubek, Tajikistan, at a depth of 10.0 km and coordinates 37.5281°, 69.9415°.
Physical scale: An earthquake of magnitude 4.8 releases seismic energy equivalent to roughly 239 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 1.2 km — a useful intuition for the size of the slip patch on the fault.
