On February 23, 2023 at 00:37 UTC, a magnitude 6.9 shallow crustal earthquake struck 65 km WSW of Murghob, Tajikistan, at a depth of 9.0 km and coordinates 38.0552°, 73.2287°. The earthquake was reported felt by 33 peopleacross nearby locations, with a maximum shaking intensity of Modified Mercalli Intensity (MMI) 7.9 (severe). The USGS PAGER system issued a green alert level for this event, indicating no significant casualties or damage expected. This earthquake was detected by 300 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 761, making it a moderate-impact event. The nearest populated place is Murghob (population 10,815).

Physical scale: An earthquake of magnitude 6.9 releases seismic energy equivalent to roughly 338 kilotons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 35 km — a useful intuition for the size of the slip patch on the fault.
