Felt by 3 people across nearby locations.
On September 23, 2025 at 22:27 UTC, a magnitude 4.6 shallow crustal earthquake struck 8 km WSW of Sındırgı, Turkey, at a depth of 27.2 km and coordinates 39.2156°, 28.0869°. This earthquake was detected by 48 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 326, placing it among routine seismic activity.
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.
