On August 27, 2024 at 07:29 UTC, a magnitude 4.9 shallow crustal earthquake struck 25 km NNE of Khorugh, Tajikistan, at a depth of 50.3 km and coordinates 37.7046°, 71.6425°. This earthquake was detected by 73 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 369, placing it among routine seismic activity.

Physical scale: An earthquake of magnitude 4.9 releases seismic energy equivalent to roughly 338 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 1.4 km — a useful intuition for the size of the slip patch on the fault.
