Santorini

Santorini is an island in the southern Aegean Sea, about 200 km (120 mi) southeast of Greece’s mainland. It is the largest island of a small, circular archipelago, which bears the same name and is the remnant of a volcanic caldera. It forms the southernmost member of the Cyclades group of islands, with an area of approximately 73 km2 (28 sq mi) and a 2011 census population of 15,550. The municipality of Santorini includes the inhabited islands of Santorini and Therasia and the uninhabited islands of Nea Kameni, Palaia Kameni, Aspronisi, and Christiana. The total land area is 90.623 km2 (34.990 sq mi).[2]Santorini is part of the Thira regional unit.[3]
Santorini is essentially what remains after an enormous volcanic eruption that destroyed the earliest settlements on a formerly single island, and created the current geological caldera. A giant central, rectangular lagoon, which measures about 12 by 7 km (7.5 by 4.3 mi), is surrounded by 300 m (980 ft) high, steep cliffs on three sides. The main island slopes downward to the Aegean Sea. On the fourth side, the lagoon is separated from the sea by another much smaller island called Therasia; the lagoon is connected to the sea in two places, in the northwest and southwest. The depth of the caldera, at 400m, makes it impossible for any but the largest ships to anchor anywhere in the protected bay; there is also a fisherman’s harbour at Vlychada, on the southwestern coast. The island’s principal port is Athinios. The capital, Fira, clings to the top of the cliff looking down on the lagoon. The volcanic rocks present from the prior eruptions feature olivine, and have a small presence of hornblende.
Tourism
The 1956 Amorgos earthquake resulted in the demolishing of many buildings in the north of Santorini, leading to the desertion of many of its villages. The expansion of tourism has resulted in the growth of the economy and population. The major settlements include Fira (Phira), Oia, Emporio, Kamari, Perissa, Imerovigli, Pyrgos, and Therasia. Akrotiri is a major archaeological site, with ruins from the Minoan era. Santorini’s primary industry is tourism, particularly in the summer months. In 2007, the cruise ship MS Sea Diamondran aground and sank inside the caldera. The island’s pumice quarries have been closed since 1986, in order to preserve the caldera. Santorini was ranked the world’s top island for many magazines and travel sites, including the Travel+Leisure Magazine, the BBC as well as the US News. An estimated 2 million tourists visit annually.
