The 2.8-km-wide island of Guguan is seen here from the NW. The island in the central Marianas Islands is composed of an eroded volcano at the south and a caldera with a post-caldera cone. A northern cone, seen here in the foreground, was the site of an eruption in the 19th century. The northern volcano has three coalescing cones and a summit crater that produced lava flows to the W and NW. Photo by Dick Moore, 1992 (U.S. Geological Survey).
