Kolumbo, Underwater volcano in Aegean Sea, Greece.

Description

Kolumbo is an active submarine volcano in the Aegean Sea northeast of Santorini. It rises from deep water toward the surface, creating a large crater with steep sides visible in sonar maps.

History

The volcano erupted in 1650, causing major changes underwater and affecting areas across the Aegean. This event shaped how people understood the geological forces in this region.

Culture

Greek maritime communities maintain records of the 1650 eruption through written accounts that detail the geological events and their effects on local populations.

Practical

The volcano sits deep underwater and cannot be seen from the surface without special equipment. Dive sites in the area allow experienced divers to explore the location and observe signs of ongoing volcanic activity.

Did you know?

Hot mineral vents on the crater floor release superheated water that would normally prevent life from existing. Yet tiny organisms have adapted to thrive in these extreme conditions.
