Volcano and Hot Springs (Nea Kameni, Palea Kameni)

Nea Kameni or "The Volcano" for locals is a volcanic island in the center of the caldera of Santorini which began to form in 1570-1573. With an area of 340 hectares and highest point of 127 meters it is the most recently created section of land in the Mediterranean Sea and along the hot springs there.

Palea Kameni is a small volcanic island area of 0.5 square kilometers with its highest point of 98.5 meters which is dated between 46 and 47 AD. Along the coast there are a lot of hot springs and every summer thousands of tourists visit the island in order to swim in the yellow waters. The main hot spring and an attraction for tourists is located in the bay of St. Nicholas.

Nea Kameni and Palea Kameni has joined the network of protected areas Natura 2000

Volcanic Activity of Palea Kameni

► 46-47 AD  The explosion of Thias, during the reign of Claudius: A explosion that created an island with a circumference of about 5600 meters (the current Palea Kameni). Because of the tsunami caused the sea in Leuven Crete fell one miles and volcanic pumice reached the coast of Asia Minor, Lesbos and Macedonia. References in this activity did Seneca, Titus Livy, Pliny the Elder, Dio Cassius, Aurelius Victor, Philostratus, the Orosius and Cassiodorus.

► 726 AD Explosion on the northeast side of Palea Kameni. Creating of an island tha quickly joined the Palea Kameni and thus made the lavas of St. Nicholas. The explosion was seen as a sign of divine wrath against the Byzantine Emperor Leo III the Isaurian, who was iconoclast. Opponents of the emperor used the event to incite rebellion, which eventually broke the 727, at the Cyclades and the rest of Greece. Leader of the Revolution was the tourmarches Greece Agallianos and Stefanos. The rebels have set another emperor, a Cretan named Cosmas and sail to Constantinople.

The fleet was destroyed by the liquid fire on 18 April 727, while the leaders of the revolution,  Agallianos was thrown into the sea, and Stephen and Cosmas delivered and beheaded.

References to the volcanic activity of this period did the victorious, Theophanes and George Kedrinos.

► 1457 AD: Collapse of a part of the island without a volcanic erruption.

Today

Research by scientists of Cambridge University, conducted in 2006, showed that if it were volcanic eruption in the islands region Palea and Nea Kameni in 2006, would have enough energy to last more than 2.7 years and build volcanic dome with a height of 115-125 meters.

In the two islands is now integrated seismic activity monitoring system which is installed by the Institute for the Study and Monitoring of the Santorini Volcano
