On September 17, 2023 at 16:23 UTC, a magnitude 4.6 shallow crustal earthquake struck 52 km SSE of Karakenja, Tajikistan, at a depth of 11.5 km and coordinates 38.8027°, 71.7603°. This earthquake was detected by 95 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 326, placing it among routine seismic activity.
Physical scale: An earthquake of magnitude 4.6 releases seismic energy equivalent to roughly 120 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 899 m — a useful intuition for the size of the slip patch on the fault.
