English: The Kone volcanic complex, also known as Gariboldi, is composed of a series of silicic calderas and young basaltic cinder cones and lava flows. North lies to the lower left in this Space Shuttle image. The dark-colored basaltic lava flows on the caldera floor were erupted during the first half of the 19th century along a hinge line between a smaller caldera on the east and a larger, 5-km-wide caldera on the west. The larger young lava flow at the right was erupted from a vent on the SE flank.
