Looking back in time: Santorini seen from Nea Kameni.

In 1707, a volcano breached the surface of the southern Aegean Sea, forming the island Nea Kameni, where this photo was taken. The circular, hundreds of thousands years old, and 400 m deep caldera in which this young volcano can be found is largely surrounded by the steep cliffs of Santorini island that itself originates from the ongoingly repeated sequence of shield volcano construction, explosive eruptions and caldera collapse. The Minoan eruption, in the mid-second millennium BC, was one of the largest volcanic events on Earth in recorded history.
