On December 23, 2025 at 04:32 UTC, a magnitude 5.1 shallow crustal earthquake struck 122 km NW of Türkmenbaşy, Turkmenistan, at a depth of 49.3 km and coordinates 40.7155°, 51.8267°. This earthquake was detected by 144 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 400, placing it among routine seismic activity.

Physical scale: An earthquake of magnitude 5.1 releases seismic energy equivalent to roughly 674 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 2.0 km — a useful intuition for the size of the slip patch on the fault.
