Earthquakes in Greece — June 2026

16 earthquakes were recorded in Greece during June 2026, an average of 0.5 per day.

16 reached magnitude 4 or above and 2 reached magnitude 5 or above. The average focal depth was 16 km.

The month's largest event in Greece was a magnitude 5.2 earthquake near Kastrí, Greece on 20 June 2026 at 09:37 UTC. A magnitude 5.2 earthquake radiates roughly 951 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 6 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 14 in the magnitude 4 range, 2 in the magnitude 5 range.

Activity peaked on 20 June, when 3 events were recorded.

The month's largest events were M5.2 near Kastrí, Greece on 20 June at 10 km; M5.1 near Prokópi, Greece on 07 June at 10 km; M4.9 near Límni, Greece on 07 June at 10 km.

That is close to the 17 events Greece averages per month across the 21 months on record.
