SPECIALS/EVENTS IN THE AEGEAN SEA
STEFANOS CRATER (NISYROS)
Nisyros´ Caldera – a geological open-air museum with millennia-old history of origins and a great connection to Greek mythology!
The Stefanos Crater on Nisyros: The volcanic crater belongs to the active volcanoes of Greece along with Methana, Santorini and Milos and is with 150,000 years the youngest active volcano of this country. Every stone on the island owes its origin to a volcanic activity.
The round island is actually just the tip of a volcano that rises out of the water. With an island diameter of 8 km there is an elliptical caldera of 4 km diameter in the middle of Nisyros, on the outer edges of which the villages have settled. Especially Emporios and Nikia offer a wonderful view.
When talking about the Nisyros volcano, one actually refers to the Stephanos crater, which with a diameter of almost 300 metres and a depth of 27 metres was "new" in the old caldera. "New" means 3,000 to 4,000 years old. The Greek “new”.
Even if the last magmatic activities are said to have taken place about 15,000 years ago, the volcanic activities have not completely ceased to exist to this day. What exactly happens? Seawater and rainwater seeping in meets a deep magma bubble. A mass of sulphur, sludge and vapour pressure is formed and pushes to the surface. The sulphurous water vapour still emerges visibly from the so-called fumaroles to the surface in the Stephanos crater. A unique natural spectacle that amazes every visitor from a safe distance.
Unlike other volcanic islands, Nisyros is rich in vegetation thanks to its fertile volcanic soil and mild climate all year round. Moreover, it is the only active volcano in the Aegean with such a rich flora and fauna.
Mythological background: It wouldn't be Greece if mythology didn't also have an exciting history of the island's origins: when Poseidon arrived on Kos during the battle of the Greek gods with the giants and persecuted the giant Polyvotis to kill him, he cut off a piece of Kos and threw it at him. This piece shattered the giant and Nisyros emerged from it. The quakes caused by the volcanic effect of the island are said to be the cry of the giant Polyvotis, who tries to be break free from the weight of the rock that has covered him for centuries.
Everybody can choose which version of the origin is more pleasing. But there is one thing that no decision needs to be made anymore: Stefanos´ Crater on Nisyros is and remains a natural phenomenon of a special kind and are worth a visit.
