The Volcano of Thira is an active volcano located in Nea Kameni Islet off the west coast of Santorini. 

The last eruption occurred in 1950, which was a relatively small one, but the most famous and destructive ones happened in the Late Bronze Age, around 1600 BC, causing the collapse of the Minoan civilization in nearby Crete. 

The caldera created by the eruption of Thira is a popular tourist attraction, with thousands of visitors coming to see the unique landscape and witness the remnants of the volcano’s destructiveness. 

Despite its active state, the volcano is closely monitored by scientists, and tourists are allowed to visit the island safely with appropriate precautions.
