Earthquakes in Greece — May 2025

13 earthquakes were recorded in Greece during May 2025, an average of 0.4 per day.

13 reached magnitude 4 or above and 3 reached magnitude 5 or above. The average focal depth was 29 km.

The month's largest event in Greece was a magnitude 6.2 earthquake near Eloúnda, Greece on 22 May 2025 at 03:19 UTC. A magnitude 6.2 earthquake radiates roughly 30,089 tons of TNT equivalent in seismic energy.

That is close to the Greece monthly average of 17 events over the period we cover, and up from the 3 recorded the previous month.

92% of events here are shallow (under 70 km), 8% 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 10 in the magnitude 4 range, 1 in the magnitude 5 range, 2 in the magnitude 6 range.

Activity peaked on 12 May, when 2 events were recorded.

The month's largest events were M6.2 near Eloúnda, Greece on 22 May at 64 km; M6.0 near Fry, Greece on 13 May at 74 km; M5.0 near Antikyra, Greece on 27 May at 10 km.

That is 22% below the 17 events Greece averages per month across the 21 months on record.

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