On March 22, 2023 at 20:07 UTC, a magnitude 5.8 shallow crustal earthquake struck 46 km NNW of Novobod, Tajikistan, at a depth of 12.0 km and coordinates 39.3830°, 69.8931°. The earthquake was reported felt by 75 peopleacross nearby locations, with a maximum shaking intensity of Modified Mercalli Intensity (MMI) 6.6 (very strong). The USGS PAGER system issued a green alert level for this event, indicating no significant casualties or damage expected. This earthquake was detected by 170 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 561, placing it among routine seismic activity. The nearest populated place is Toguz-Bulak (population 0).

Physical scale: An earthquake of magnitude 5.8 releases seismic energy equivalent to roughly 8 kilotons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 6.1 km — a useful intuition for the size of the slip patch on the fault.
