sulpherous fumerole, volcano on Nisyros in the Aegean sea greece
A fumarole (Latin fumus, smoke) is an opening in Earth's (or any other astronomical body's) crust, often in the neighborhood of volcanoes, which emits steam and gases such as carbon dioxide, sulfur dioxide, hydrochloric acid, and hydrogen sulfide. The name solfatara, from the Italian solfo, sulfur (via the Sicilian dialect), is given to fumaroles that emit sulfurous gases. Nisyros (Greek: Νίσυρος; also transliterated Nissiros; Italian: Nisiro) is a volcanic Greek island and municipality located in the Aegean Sea. It is part of the Dodecanese group of islands, situated between the islands of Kos and Tilos. Its shape is approximately round, with a diameter of about 8 km, and an area of km². Several other islets are found in the direct vicinity of Nisyros, the largest of which is Gyali. The volcano is currently active (not erupting), and fumaroles are found at the craters. The latest eruptive activity was a steam explosion in 1888, after small ash eruptions in 1871 and 1873 and earthquakes are not infrequent. A period of seismic unrest in 1996-1997 led an international team of scientist to initiate monitoring of the volcanic unrest in the European-Union sponsored Geowarn project. The entire volcanic complex includes the seafloor between Nisyros and Kos, the island of Gyali, and a part of Kos island. According to Greek mythology, the island was formed when Poseidon cut off a part of Kos and threw it onto the giant Polyvotis to stop him from escaping. The ancient name of the Nisyros was Porphyris. Ancient walls, dating from the 5th century BC, part of the acropolis of the island, are found near Mandraki.
