Kolumbo submarine volcano is situated just to the north-east of Thera, and it erupted in 1650. We have discovered that there are about twenty other volcanic cones to the north-east of Kolumbo, forming a line of volcanoes.

This is an important discovery and it shows that the Thera volcanic field is much larger than thought previously. The figure above shows a seismic profile across one of these new cones, which we hope to explore further with the Max-Rover ROV in the next few days.
