About the volcano

Santorini is a sea-flooded caldera whose rim is formed by the islands of Thira, Thirasia and Aspronisi. In the Bronze Age, in the second millennium BCE, it produced the Minoan eruption – one of the largest in human history. Pumice and ash buried the town of Akrotiri, whose well-preserved ruins were excavated in the 20th century. The exact date of the eruption is still debated: radiocarbon dating and archaeological evidence differ by more than a century. Later, smaller eruptions built the islets of Palea and Nea Kameni in the middle of the caldera; the most recent was in 1950.

Eruption history

VEI – Volcanic Explosivity Index: 0 = lava outpouring, 4 = like Eyjafjallajökull 2010, 6 = like Pinatubo 1991, 7 = like Tambora 1815. The scale is logarithmic – each step is about 10 times more material.
