On November 4, 2020 at 17:51 UTC, a magnitude 4.5 shallow crustal earthquake struck 22 km SSE of Kyurdarmir, Azerbaijan, at a depth of 59.8 km and coordinates 40.1588°, 48.2776°.

Physical scale: An earthquake of magnitude 4.5 releases seismic energy equivalent to roughly 85 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 767 m — a useful intuition for the size of the slip patch on the fault.
