From Wikipedia

Kolumbo (Greek: Κολούμπο) 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.
