Photo Gallery


The Ischia volcanic complex forms a 6 x 9 km island at the western side of the Bay of Naples. The tip of the island of Procida, ENE of Ischia, is visible at the left in this Space Shuttle image. Tectonism has influenced volcanic activity at Ischia, and its high point (the dark-colored area at the center of the island) is a volcanic horst composed of ignimbrite deposits associated with Pleistocene caldera formation. During the Holocene, a series of pumiceous tephras, tuff rings, lava domes, and lava flows were erupted.
