The volcano is what made Santorini what it is today.
It continues to rule the caldera and attracts the
attention of all visitors.
Here is what happened in a few words:
A huge eruption around 1650 BC, one of the largest
in the last 10.000 years, followed by a collapse
created the caldera. It was the same eruption that
destroyed the Minoan civilization. Several eruptions
later formed two small islands inside the caldera
called Palea Kameni (Old Burnt in Greek) and Nea
Kameni (New Burnt) as they are today.
Caldera - Created with the big
VEI 6 minoan eruption of about 1650 BC Palea Kameni - Formed with several
eruptions during 197 BC and 1458 AD Nea Kameni - Formed by the eruption
detween 1707 AD and 1950 AD
What the locals call the volcano is Nea Kameni island.
Anyone can visit both Nea Kameni and Palea Kameni
with one of the daily cruises sold at all travel
agencies on the island, step his foot upon the youngest
part of Europe (Nea Kameni last part was formed
in 1939 and 1950) and swim in the hot
springs of Palea Kameni.
