On October 20, 2021 at 15:05 UTC, a magnitude 4.4 shallow crustal earthquake struck 12 km NNW of Van, Turkey, at a depth of 10.0 km and coordinates 38.6076°, 43.3512°.
Physical scale: An earthquake of magnitude 4.4 releases seismic energy equivalent to roughly 60 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 655 m — a useful intuition for the size of the slip patch on the fault.
