Details for: Guguan
The small island of Guguan is seen here in an aerial view from the NW. The 2.8-km-wide 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 volcano seen here in the foreground, was the site of the only historical eruption of Guguan in the 19th century. The northern volcano has three coalescing cones and a breached summit crater that fed lava flows to the west and NW. The 287-m high point of the island is the south rim of the caldera.
