A truly beautiful and amazing place for me- the Nisyros Volcano at Nisyros Island. This volcanic island is part of the Dodecanese Islands.The volcano has a 4 km wide caldera.

The Nisyros volcano is the most active remain of the Cos caldera that exploded aprox. 150.000 years ago. Nisyros, Yali, Strongyli, Pyrgoussa, Pahia and Kefalos (at Cos) are the remains of a zone that is considered to be still active. A Magma chamber below Nisyros is only 3-4 km deep and still rising up.
