Earthquakes in Greece — December 2024

12 earthquakes were recorded in Greece during December 2024, an average of 0.4 per day.

11 reached magnitude 4 or above and 2 reached magnitude 5 or above. The average focal depth was 31 km.

The month's largest event in Greece was a magnitude 5.2 earthquake near Ierápetra, Greece on 22 December 2024 at 19:09 UTC. A magnitude 5.2 earthquake radiates roughly 951 tons of TNT equivalent in seismic energy.

That is below the Greece monthly average of 16 events over the period we cover — a comparatively quiet month, and up from the 1 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 1 in the magnitude 2 range, 9 in the magnitude 4 range, 2 in the magnitude 5 range.

Activity peaked on 13 December, when 2 events were recorded.

The month's largest events were M5.2 near Ierápetra, Greece on 22 December at 10 km; M5.0 near Αγρίνιο, Greece on 21 December at 10 km; M4.9 near Άγιον Όρος, Greece on 13 December at 10 km.

That is 26% below the 16 events Greece averages per month across the 22 months on record.
