After living in California on the San Andreas fault, I never realized how many people did not know how dangerous it was and all of the misconceptions people had about the fault. Before I started taking geology classes, I was definitely one of those people. I knew that it was there, but I really did not know much about it. I didn’t know the risks … Continue reading A Beautiful Place with a Frightening Reality
The Peresteria composite cone once stood high on the horizon of the Aegean. It was a prominent feature on the landscape and graced the stratosphere with its peak. Peresteria was the first subaerial volcanic feature to appear in the northern part of Thera on a major fault system known as the Colombo Line. Since its construction, it has been blown up by four caldera forming eruptions, and covered by numerous lava flows. In its exposed interior, Peresteria shows the geologic history of the island and holds the key to Santorini’s complex past.

I’ve just learned the full story of the Minoan eruption. In my mind, I’m imagining 60 cubic kilometers of earth. This is about the size of a block of the Los Angeles basin, by volume; a massive amount of land. I can see all this land being ejected by the volcano miles into the sky, over a span of 24 hours. Such is the case of Santorini’s last caldera forming eruption. Continue reading “Moving Megatons: The Excavational Eruptions of Calderas”
During my time here in Santorini I have done a lot of thinking. Thinking about life, volcanoes, and most of all trying to wrap my head around the earth that I am standing on. I have found a spot of my own here, it is off a beaten path, where no one goes and it has incredible view of the Kameni shield volcanoes. I have sat there for hours just trying to imagine the transitions and the magnificent power behind the construction of Santorini. There were many processes and five phases that have contributed to building this beautiful island, but the final phase, also known as phase four, and the phase I will be focusing on in this paper was catastrophic, the exit of this eruption was nothing short of grand.
The 1613 +/-13 BC Minoan eruption is known worldwide for its colossal eruption that was nearly equal to the eruptions of Tambora and Krakatau in Indonesia. We are studying this specific eruption because while it greatly effected the morphology of Santorini, the population of the island was effected as well (1). This eruption is crucial in our understanding of future caldera eruptions and expands our knowledge of the likelihood of another eruption.
