M6.0 Earthquake 7 km SE of Sındırgı, Turkey — October 27, 2025
2025-10-27 19:48:28 UTC (2025-10-27) · approx. 9:48 PM UTC+2 local
Felt by 193 people across surrounding communities. Maximum shaking intensity MMI 8.1 (violent).
On October 27, 2025 at 19:48 UTC, a magnitude 6.0 shallow crustal earthquake struck 7 km SE of Sındırgı, Turkey, at a depth of 8.0 km and coordinates 39.1937°, 28.2425°. The earthquake was reported felt by 193 peopleacross surrounding communities, with a maximum shaking intensity of Modified Mercalli Intensity (MMI) 8.1 (violent). The USGS PAGER system issued a yellow alert level for this event, indicating local impact possible. This earthquake was detected by 130 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 799, making it a moderate-impact event. The nearest populated place is Sindirgi (population 10,907).
Physical scale: An earthquake of magnitude 6.0 releases seismic energy equivalent to roughly 15 kilotons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 8.3 km — 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 6.0 earthquakes can continue for weeks to months 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 6.0 event is significantly smaller than that historical record.
What should I do after an earthquake?
If you were in the affected area: check yourself and others for injuries, inspect your home for damage, and be prepared for aftershocks. For detailed guidance, see our earthquake safety guide and emergency planning resources.
