Volcanoes in profile – Greece

Short descriptions of the country's best-known volcanoes.

Milos

Stratovolcano · 751 m · Last eruption: 140

Milos or Melos is a volcanic Greek island in the Aegean Sea, just north of the Sea of Crete. It is the southwestern-most of the Cyclades islands.

Santorini

Shield volcano · 367 m · Last eruption: 1950

The Santorini caldera is a large, mostly submerged volcanic caldera located in the southern Aegean Sea, 120 kilometers north of Crete in Greece. Visible above water is the circular Santorini island group, consisting of the main island of Santorini, Therasia and Aspronisi at the periphery, and the Kameni islands at the center. It has been designated one of the world's sixteen Decade Volcanoes.

Kolumbo

Volcanic complex · -18 m · Last eruption: 1650

Kolumbo is an active submarine volcano in the Aegean Sea in Greece, about 8 km (5.0 mi) northeast of Cape Kolumbo, Santorini (Thira) island. The largest of a line of about twenty submarine volcanic cones extending to the northeast from Santorini, it is about 3 km (1.9 mi) in diameter with a crater 1.5 km (0.93 mi) across. It was first noticed by humans when it breached the sea surface in 1649–1650. The Smithsonian Institution's Global Volcanism Program treats it as part of the Santorini volcano, though at least one source maintains that it is a separate magmatic system.

Frequently asked questions about volcanoes in Greece

How many volcanoes are there in Greece?
The Holocene catalogue of the Smithsonian Global Volcanism Program lists 5 volcanoes in Greece. It covers volcanoes with eruptions during the last roughly 12,000 years.
Which volcano in Greece is the highest?
The highest recorded volcano is Milos at 751 m.
When was the last documented eruption in Greece?
The most recent eruption documented in the catalogue dates from 1950 (Santorini).
Are the volcanoes in Greece active?
None of the 5 volcanoes currently has an eruption report. That does not mean they are extinct – source coverage differs from volcano to volcano.
Why does the map show aircraft around volcanoes?
Volcanic ash endangers aircraft engines. The map therefore shows live positions within 50 km of a volcano so that the proximity of air traffic to an active volcano becomes visible.
Where does the data on this page come from?
Catalogue data and eruption history from the Smithsonian Global Volcanism Program, significant eruptions from NOAA NCEI, alert levels and bulletins from USGS, GeoNet and INGV, earthquakes from the QuakeMap24 database, flight positions from ADSB.lol.
