Earthquakes in Greece — June 2025

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

13 reached magnitude 4 or above and 1 reached magnitude 5 or above. The average focal depth was 33 km.

The month's largest event in Greece was a magnitude 5.3 earthquake near Karyes, Greece on 07 June 2025 at 12:46 UTC. A magnitude 5.3 earthquake radiates roughly 1,344 tons of TNT equivalent in seismic energy.

That is close to the Greece monthly average of 17 events over the period we cover, and level with the 13 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 12 in the magnitude 4 range, 1 in the magnitude 5 range.

Activity peaked on 07 June, when 2 events were recorded.

The month's largest events were M5.3 near Karyes, Greece on 07 June at 10 km; M4.9 near Palaióchora, Greece on 20 June at 41 km; M4.9 near Kentrí, Greece on 03 June at 40 km.

That is 23% below the 17 events Greece averages per month across the 21 months on record.
