Felt by 13 people across nearby locations.
On January 10, 2021 at 19:53 UTC, a magnitude 4.3 shallow crustal earthquake struck 11 km W of Kalecik, Turkey, at a depth of 10.0 km and coordinates 40.1163°, 33.2748°.
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.
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.
