My Geologic Adventure to Oια
June 6, 2018
Dear Diary,
Today we went on an amazing hike from the base of Peresteria volcano to the city of Οια (ee-Yah) in Santorini, Greece to broaden our knowledge on volcanic formations. We arrived on the outskirts of Οια approximately at 11:03 a.m., which was early enough to experience a light breeze from the north.

Honestly, someone should have warned a big girl like me. Despite all the stress of hiking the class came across some interesting formations along the way. Keep Reading!

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.

Cut scene: Phase 0
In most horror films there is a warning scene right before everything goes down hill. You sit on the edge of your seat and shout at the group not to go into the basement for there is disaster lurking below. However, it is the characters’ decision whether to investigate the noise or get out as fast a possible. In the case of the Minoan eruption the earthquakes and phase 0 are the warning scene. In most horror or thriller films the main character walks toward the impending threat. However this is not the fate for the Minoans, or so we believe.
