On March 11, 2023 at 19:35 UTC, a magnitude 4.3 shallow crustal earthquake struck 11 km SW of Ceyhan, Turkey, at a depth of 3.7 km and coordinates 36.9506°, 35.7349°.

Physical scale: An earthquake of magnitude 4.3 releases seismic energy equivalent to roughly 43 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 558 m — a useful intuition for the size of the slip patch on the fault.
