Stephanos crater of Nisyros volcano
The small round island of Nisyros is one of the more active but less known volcanoes in Greece. It is located south of the popular beach holiday island of Kos.
The last eruption of Nisyros were phreatic explosions in 1881-87. They left a moonscape with colorful craters and very active fumaroles.

Introduction
Nisyros volcano is part of the Hellenic Arc, a curved line of volcanic centers caused by the subduction zone where the African tectonic plate sinks under under the Aegean microplate, which in turn is part of the larger Eurasian tectonic plate. The arc stretches from the Saronic Gulf opposite Athens via the island groups of Milos, Santorini, and Nisyros-Yali-Kos to the Bodrum peninsula at the extreme SW of Turkey.Together with the volcanoes of the Kos caldera, Nisyros forms the most important volcanic center of the eastern section of the Hellenic arc.
Nisyros volcano itself is the most recently active part of the Kos caldera, which had formed during a massive ultra-plinian eruption approx. 150.000 years ago. Nisyros, Yali, Strongyli, Pyrgoussa, Pahia and Kefalos (at Kos) are the present-day centers of this caldera system that can be considered to be still active.
At Nisyros, an active magma chamber is located at only 3-4 km depth. Since 2000 when the Nisyros research program of the GEOWARN-Team started, the temperatures of the fumaroles have been changing from 98 C to 103 C in 2004.

Remark:
Our list of volcanic eruptions closely follows the database of eruptions of the Smithsonian's Global Volcanism Project (GVP), the internationally most recognized data source for volcanic eruptions, but also includes significant eruptive episodes or related volcano events. "Volcanic eruptions" are usually to be understood as sequences of individual eruptive episodes that can follow each other, or even overlap (if several vents are involved), and can last many years, decades or even longer. For example, the current activity of Stromboli volcano is understood as a single eruption that has been ongoing since 1934.
