As I walk the streets of Fira, Santorini and swim through the waves of tourists I see that most of them look out towards the center of the caldera. To them this island has always looked this way. Many know that around 1613 BC there was a cataclysmic eruption that forms the present day caldera and was a leading factor to the end of the Minoan civilization. Although they understand this, they do not realize that three cataclysmic caldera forming eruptions preceded the Minoan eruption and that even in the thousands of years in between each eruption the geography was constantly changing and morphing through volcanism and erosion into new shapes. As our class hiked around Thera, I saw before my eyes the different parts of this complex past that make it the paradise that it is today.
