M4.5 Earthquake 12 km NW of Urla, Turkey — July 16, 2020
2020-07-16 18:09:26 UTC (2020-07-16) · approx. 8:09 PM UTC+2 local
On July 16, 2020 at 18:09 UTC, a magnitude 4.5 shallow crustal earthquake struck 12 km NW of Urla, Turkey, at a depth of 10.0 km and coordinates 38.4031°, 26.6668°.
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.
