Earthquakes in Turkey — October 2025

13 earthquakes were recorded in Turkey during October 2025, an average of 0.4 per day.

13 reached magnitude 4 or above and 2 reached magnitude 5 or above. The average focal depth was 14 km.

The month's largest event in Turkey was a magnitude 6.0 earthquake near Sındırgı, Turkey on 27 October 2025 at 19:48 UTC. A magnitude 6.0 earthquake radiates roughly 15,080 tons of TNT equivalent in seismic energy.

That is well above the Turkey monthly average of 6 events over the period we cover — an unusually active month, and up from the 9 recorded the previous month.

100% of events here are shallow (under 70 km), 0% intermediate (70–300 km) and 0% deep-focus (over 300 km). Almost everything here is crustal. That is characteristic of transform faulting or continental deformation rather than subduction — and it means shaking at the surface is strong for the magnitudes involved.

By band, the catalogue holds 11 in the magnitude 4 range, 1 in the magnitude 5 range, 1 in the magnitude 6 range.

Activity peaked on 28 October, when 5 events were recorded.

The month's largest events were M6.0 near Sındırgı, Turkey on 27 October at 8 km; M5.0 near Marmara Ereğlisi, Turkey on 02 October at 10 km; M4.9 near Sındırgı, Turkey on 28 October at 10 km.

That is 110% above the 6 events Turkey averages per month across the 21 months on record.
