On March 29, 2023 at 20:08 UTC, a magnitude 4.1 shallow crustal earthquake struck near Central Turkey, at a depth of 3.9 km and coordinates 37.3405°, 36.8426°.

Physical scale: An earthquake of magnitude 4.1 releases seismic energy equivalent to roughly 21 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 406 m — a useful intuition for the size of the slip patch on the fault.
