On September 3, 2023 at 16:35 UTC, a magnitude 4.9 shallow crustal earthquake struck 7 km ESE of Kyurdarmir, Azerbaijan, at a depth of 68.3 km and coordinates 40.3087°, 48.2270°. This earthquake was detected by 79 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 374, 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.
