Background
The island of Kos is dominantly non-volcanic but contains Miocene to Pleistocene volcanic centers. The Kamari caldera is of mid-Pleistocene age and contains the 1.0-0.55 million-year-old, post-caldera Zini lava dome. The formation of a large caldera deposited the widespread Kos Plateau Tuff (erupted about 160,000 years ago), which blankets much of the western half of Kos and originated from a stratovolcano between Kos and Nisyros islands. The caldera dimensions are uncertain, but may extend as much as 20 km from Kefalos Bay in SW Kos Island to Nisyros Island. Remnants of the pre-eruption stratovolcano are preserved on the islets of Pachia and Pyrgousa and as submarine volcanic rocks on Nisyros. Kos was included in the Catalog of Active Volcanoes of the World (Georgalas, 1962) based on its geothermal activity. Several solfatara fields are present, including Vromotopos at Kefalos Isthmus on the western side of the island and a group of thermal areas at the eastern side of Kos. Thermal activity consists of weak hydrogen sulfide emission, sulfur deposits, and two hot springs along the southeastern coast.---
