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