Earthquakes in Turkey — April 2025

15 earthquakes were recorded in Turkey during April 2025, an average of 0.5 per day.

15 reached magnitude 4 or above and 3 reached magnitude 5 or above. The average focal depth was 13 km.

The month's largest event in Turkey was a magnitude 6.2 earthquake near Marmara Ereğlisi, Turkey on 23 April 2025 at 09:49 UTC. A magnitude 6.2 earthquake radiates roughly 30,089 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 5 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 12 in the magnitude 4 range, 2 in the magnitude 5 range, 1 in the magnitude 6 range.

Activity peaked on 23 April, when 5 events were recorded.

The month's largest events were M6.2 near Marmara Ereğlisi, Turkey on 23 April at 10 km; M5.0 near Kumburgaz, Turkey on 23 April at 10 km; M5.0 near Silivri, Turkey on 23 April at 10 km.

That is 142% above the 6 events Turkey averages per month across the 21 months on record.

This month also holds the strongest earthquake recorded in Turkey in our entire catalogue.
