    Kolumbo breached the sea surface in 1649–1650. The 1650 eruption sent pyroclastic flows toward Santorini, causing significant loss of life.

Background and detail

Geological Context. Kolumbo is an active submarine volcano located about 8 km northeast of Cape Kolumbo on Santorini. It is the largest of a line of twenty submarine cones and is treated by the Global Volcanism Program as part of the Santorini volcano system, though some sources view it as separate.

Eruption Impact. The volcano first breached the surface in 1649–1650. The 1650 eruption, occurring when the cone reached the surface, sent pyroclastic flows to Santorini, killing about seventy people and many animals. Superheated water from the vents has since built polymetallic sulfide chimneys up to 4 meters high.
