BeschreibungThe large hydrothermal field in the northern part of the caldera at about 500 m depth contains a massive Kuroko-style sulfide deposit. Only few such deposits are known world-wide and they are of great interest, especially because of the typically high content of gold and silver in the sulfides. In 2010, the exploration Vessel (E/V) Nautilus discovered steep, up to 6 m high chimneys of sulfides above one of the vents.
1650 eruption of Kolumbo volcano
The 1650 eruption was a very explosive event and ejected pumice and ash as far as Turkey, and produced pyroclastic flows that killed about 70 people on Santorini. During the eruption, it constructed a temporary island (hence it's name Kolumbo, in Greece "swimming"). A tsunami occurred as well, probably during the collapse of the cone. It caused damage on nearby islands up to 150 km and invaded the flat coastal areas especially on the eastern side of Santorini, where ruins from Roman times were uncovered. The eruption also caused damage killed a great number of livestock because of poisonous gasses, mainly H2S.
