Nisyros & Geology
It dates back to the ancient years but it is the newest large active volcano in the Aegean Sea: its oldest rocks are about 150,000 years old while its newest are almost 15,000 years old. Together with Methana, Milos and Santorini, it is considered a part of the active volcanic arc of the Aegean. There are ten craters on the bottom of the caldera (which is not underwater!), the largest of which is Stefanos, with an impressive diameter of 330 meters and intense hydrothermal activity. However, the entire island of Nisyros is a huge volcanic edifice, as every stone and rock was created as a result of the volcanic activity.
The large variety in the composition and forms of the rocks making up the island, the extensive and easily accessible natural sections and the wonderful climate throughout the year make Nisyros an outdoors geological museum!
The Volcanological Museum
The first volcanological museum of Greece is situated in Nikeia, Nisyros and aims at introducing the visitors to the amazing but unknown world of geology and volcanoes. The exhibition itself reminds us of a true volcanic landscape and transfers the visitors inside the volcano!
