Gate with Kameni In the center of the caldera are two islets forming from the volcano, Kameni and Paleo Kameni. They are built out of the lava flows emenating periodically from the magma chamber below. This view is taken from the caldera cliff in Fira, and you can see the larger of the two islets in the middle of the image. ![]() Copyright 2008, J. S. Pezaris AREADNE | Email | Archive |
