Blue Greece

Santorini is a small, circular group of volcanic islands located in the Aegean Sea, about 200 km south-east from the mainland of Greece. It is also known by the name of the largest island in the archipelago, Thira or Thera. It is the southernmost member of the Cyclades group of islands, with an area of approximately 73 km² (28 sq mi), and in 2001 had an estimated population of 13,600. The inhabitants are citizens of Greece and speak Greek. It is the most active volcanic centre in the Aegean Arc, though what remains today is largely a caldera.

The name Santorini was given to it by the Venetians in the 13th century and is a reference to Saint Irene. Before then it was called Kallisti, Strongili or Thera. The island was the site of one of the largest volcanic eruptions of the last several thousand years when it erupted cataclysmically about 3,500 years ago. The eruption left a large caldera surrounded by ash deposits hundreds of feet deep, and its effects may have indirectly led to the collapse of the Minoan civilization on the island of Crete, 70 km to the south.

Modern Santorini

Santorini was annexed to Greece in 1912. Major settlements in Santorini include Fira (Phira),Oia, Emporio, Kamari, Imerovigli, Pyrgos and Therasia. Akrotiri is a major archaeological site with ruins from the Minoan era. The island has no rivers and water is scarce. Until the early nineties locals used to fill water tanks from the rain that fell on their roofs and courts, from small springs as well as by importing it from other areas of Greece.

Nowadays, there is a desalination plant that provides running, yet nonpotable, water to most houses. The primary industry of Santorini is tourism. The pumice quarries have been closed since 1986 in order to preserve the caldera of Santorini.

Santorini is home to a small but flourishing wine industry, based on the indigenous grape variety,
Assyrtiko. Assyrtiko vines are extremely old, as they are resistant to phylloxera and have consequently not needed to be replaced during the great phylloxera epidemic of the early 20th century. They are adopted to their native habitat by being planted far apart and their principal source of moisture is dew. They are trained in the shape of baskets, with the grapes hanging inside to protect them from the winds.

In 1704 an undersea volcano breached the sea surface forming the current centre of activity at Nea Kameni, and eruptions centred on it continue—three times in the twentieth century, the last being in 1950. Santorini was also struck by a devastating earthquake in 1956.
