The volcanic field of Santorini consists of Santorini, the Christiania islands around 20 km to the southwest and the submerged Columbus volcano 7 km to the northeast. It is partly situated on a southwest - northeast trending tectonic horst called the Amorgos Ridge.

Santorini caldera is a large, mostly submerged caldera, located in the southern Aegean Sea, 120 kilometers north of Crete in Greece.Visible above water is the circular Santorini island group, consisting of Santorini (classic Greek Thera), the main island, Therasia and Aspronisi at the periphery, and the Kameni islands at the center. It has been designated a Decade Volcano.

Dec 8, 1999 · Santorini is one of several Quaternary volcanoes that define the present day active volcanic arc related to this subduction zone (Fig. 2.1). We here provide a synopsis of the broader geological and tectonic context of Santorini within the Aegean area.
