On August 4, 2020 at 18:40 UTC, a magnitude 4.5 shallow crustal earthquake struck 24 km NNE of Sincik, Turkey, at a depth of 10.0 km and coordinates 38.2374°, 38.7315°.

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.

The epicenter is located in Turkey, a region characterized by the North Anatolian Fault, a 1,500 km transform boundary driven by the westward extrusion of the Anatolian microplate. The nearest mapped fault system is the North Anatolian Fault. View all earthquakes in Turkey.
