Santorini (Thira) day trip

Santorini is a volcano. The towns line the tops of the high cliffs, with spectacular views into the centre of the volcano. The last major earthquake that measured 7.8 was in 1956 - they also watch for slight changes in the rise or fall of the central land mass as a determinor of a forthcoming eruption(they say they can tell a month in advance of a possible eruption).

We caught a ferry from Naxos.
