M4.3 Earthquake in the Turkey-Iran border region — August 11, 2020
2020-08-11 23:29:09 UTC (2020-08-11) · approx. 2:29 AM UTC+3 local
Felt by 26 people across nearby locations.
On August 11, 2020 at 23:29 UTC, a magnitude 4.3 shallow crustal earthquake struck in the Turkey-Iran border region, at a depth of 10.0 km and coordinates 39.8510°, 44.1997°.
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.

Were there aftershocks?
Aftershock activity is monitored continuously by the USGS. Aftershock sequences from magnitude 4.3 earthquakes can continue for several days and gradually diminish over time.
Has Turkey had earthquakes this big before?
The largest recorded earthquake in Turkey was the M7.8 Kahramanmaraş earthquake of February 6, 2023. Today's magnitude 4.3 event is significantly smaller than that historical record.
