Koloumbos Volcano

Underwater Volcano

The eruption of the underwater volcano Koloumbos - which is connected to the activity of Santorini's volcano since it's situated only 8klm from it - took place in September 1650 and lasted two months! It was the biggest eruption taking place in the Eastern Mediterranean in the last 1000 years.

The strong earthquakes and spurting of volcanic ashes and poisonous gases made Santorini suffer massive destruction in its cattle-breeding and cultivations as well as the tragic death of 50 people.

In order to exorcise the evil spirits, the residents of Santorini built a church near the cape of Koloumbos, which they called “Panagia tou Kalou” (Mary of Kindness). The erruption created a reef, which was named Koloumbos.

It took its name after its appearance since in Italian, it means dove; unlike the volcanoes of Old and New Kameni who are black, Koloumbos stands in brilliant white, just like a dove. The reef's base sits at a depth of 300m while its top has been corroded by seawater and stands only 18m away from its surface!
