How deep are earthquakes within 250 km of Athens?

100% of the magnitude 2.5+ earthquakes recorded within 250 km of Athens in the last 30 days were shallower than 70 km. Shallow earthquakes generally cause stronger shaking at the surface than deep ones of the same magnitude.

Where can I get official earthquake information for Greece?

For official information, warnings and safety advice, follow National Observatory of Athens (https://www.gein.noa.gr/en/) and your local civil protection authority. This site compiles agency reports and is not a warning service.

Can earthquakes be predicted?

No. Scientists can estimate how likely strong shaking is in a region over years or decades, but no method predicts the time, place and size of a specific earthquake. Aftershocks are expected after large earthquakes and become less frequent over time.
