Global Volcanism Program | Image GVP-10460

The 50-km-long island of Umboi, the largest of the volcanic islands off the north coast of New Guinea, is seen in this Space Shuttle image (N is to the top-right). A large 13 x 17 km caldera is visible in the northern half of the island and is breached to the NE (top center). Three post-caldera cones with summit crater lakes (left center) are visible on the smooth-surfaced caldera floor. The large eroded massif (right center) is an older volcanic complex, as is the dissected northern tip of the island (upper left).
