Felt by 5 people across nearby locations.
On July 25, 2021 at 20:55 UTC, a magnitude 4.6 shallow crustal earthquake struck 9 km W of Hasanbeyli, Turkey, at a depth of 10.0 km and coordinates 37.1114°, 36.4369°.
Physical scale: An earthquake of magnitude 4.6 releases seismic energy equivalent to roughly 120 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 899 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.
