Nisyros

 island, volcano

Nisyros also spelled Nisiros (Greek: Νίσυρος, Nísiros) 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 (5 mi), and an area of 41.6 km2 (16.062 sq mi). Several other islets are found in the direct vicinity of Nisyros, the largest of which is Gyali, with a population of 22 citizens. The Municipality of Nisyros includes Gyalí, as well as uninhabited Pacheiá, Pergoússa, Kandelioussa, Ágios Antónios and Stroggýli. It has a total land area of 50.055 km2 (19.326 sq mi) and a total population of 1,008 inhabitants. The island was also called Nisiro in Italian.
The island is reachable by ship from Piraeus and Kos, and in summer, there are many daily trips from the village of Kardamena on Kos. There is also a heliport. The main town and port of the island is Mandraki (pop. 660). Other villages are Paloi (239), Nikia (61), and Emporeios (27). According to the 2011 census, the municipality's resident population is 1,008 (including 21 on Gyali), although in summer it is augmented by many tourists as well as expatriate Nisyrians who visit the island for their vacations. Tourism is not so heavily developed as on other Greek islands. Deposits of perlite and pumice on Gyali provide much of the wealth of the island. The island used to be self-sufficient, and many crops were grown on its terraced slopes. Today, though, they are cultivated on a smaller scale.
