Kolumbo is an active submarine volcano in the Aegean Sea in Greece, about 8 km northeast of Cape Kolumbo, Santorini island. The largest of a line of about twenty submarine volcanic cones extending to the northeast from Santorini, [1] it is about 3 km in diameter with a crater 1.5 km across. [2] It was first noticed by humans when it breached the sea surface in 1649–1650.

The submarine Kolumbo volcano is about 15 km NE of the center of the Santorini caldera. Although previously considered to be part of a volcanic field associated with Santorini along a fault zone, Klaver et al. (2016) concluded that Kolumbo was a distinct volcanic system with 'a deep differentiation history' based on 'a signature of high 208Pb/206Pb compared to Santorini'. A …
