Santorini Island is the site a volcanic eruption about 3,600 years ago. The eruption left a large caldera surrounded by volcanic ash deposits hundreds of metres deep. We took this image from the east rim that illustrates the distance to the west rim (in the background).
While climbing the central peak of the Santorini volcano, I noticed these “look-a-like” shatter cones. The volcanic explosion may have been of sufficient magnitude to form shatter cones, but these may be tephra (rock fragments ejected from the eruption).
