About Earthquake Activity in Greece
Greece is the most seismically active country in Europe, particularly in the Aegean region. Learn more about seismic activity in Greece below.
The largest earthquake recorded in Greece in the past 100 years was M7.7 in 1956 (19 km SSE of Amorgós, Greece). The region is defined by Hellenic Arc, North Aegean Trough, Corinth Rift, and the risk level is classified as High.
With a population of 10.4 million, understanding local seismic hazards is crucial. This page provides real‑time USGS data and historical context for Greece.
Why does Greece experience earthquakes?
Greece lies on Aegean Sea microplate, subduction of African Plate. The movement of these plates builds up stress, which is released as earthquakes. In subduction zones, one plate dives beneath another, generating some of the largest quakes on Earth. In strike‑slip regions like the San Andreas, plates slide past horizontally.

Frequently Asked Questions about Greece Earthquakes
❓ What was the strongest earthquake in Greece?
The largest earthquake recorded in Greece in the past 100 years was M7.7 in 1956 (19 km SSE of Amorgós, Greece).
❓ Is Greece on a fault line?
Yes, Greece is crossed by Hellenic Arc, North Aegean Trough, Corinth Rift, making it prone to seismic activity.
❓ How often do earthquakes occur in Greece?
Due to its tectonic setting (Aegean Sea microplate, subduction of African Plate), Greece experiences hundreds to thousands of earthquakes each year, though most are too small to feel.
❓ What should I do during an earthquake in Greece?
Drop, cover, and hold on. Stay away from windows, and if outdoors, move to an open area. After the shaking stops, check for injuries and be ready for aftershocks.
