Earthquakes in Turkey

Turkey appears infrequently in the record, with just 2 events in the past 30 days, and 18 of the events on record reached magnitude 5 or above — the level at which damage becomes a genuine concern for vulnerable construction. Activity here is almost entirely crustal, which means shaking at the surface is strong relative to the magnitudes involved.

130 earthquakes have been recorded in Turkey in our catalogue, 2 of them in the past 30 days.

The average magnitude is 4.5 and the average focal depth 17 km. 128 events reached magnitude 4 or above and 18 reached magnitude 5 or above.

The strongest earthquake recorded in Turkey in this period was a magnitude 6.2 event near Marmara Ereğlisi, Turkey on 23 April 2025, at a depth of 10 km. A magnitude 6.2 earthquake radiates roughly 30,089 tons of TNT equivalent in seismic energy.

Locations recording the most events include Sındırgı (42), Simav (6), Kaş (5), Sincik (4), Kumburgaz (4).

95% of events here are shallow (under 70 km), 5% 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.

The deepest event on record here was a magnitude 5.1 earthquake at 113 km beneath Kocaaliler, Turkey on 08 December 2025.

By band, the catalogue holds 2 in the magnitude 3 range, 110 in the magnitude 4 range, 15 in the magnitude 5 range, 3 in the magnitude 6 range.

The busiest single day was 10 November 2025, with 5 recorded events.

No event in this record carries a USGS link to NOAA tsunami information.
