On August 16, 2023 at 01:37 UTC, a magnitude 5.1 shallow crustal earthquake struck 31 km NNE of Türkmenbaşy, Turkmenistan, at a depth of 50.6 km and coordinates 40.2712°, 53.1430°. This earthquake was detected by 132 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 402, 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.
