Australia-Oceania :: Vanuatu
Caption
Periodically active volcano Mt. Manaro is the dominant feature in this shaded relief image of Aoba (Ambae) Island, part of the Vanuatu Archipelago located 2,250 km (1,400 mi) northeast of Sydney, Australia. The 1,496 m (4,908 ft) high Hawaiian-style basaltic shield volcano features two lakes within its summit caldera, or crater. Two visualization methods were combined to produce the image: shading and color coding of topographic height. The shade image was derived by computing topographic slope in the northwest-southeast direction, so that northwest slopes appear bright and southeast slopes appear dark. Color coding is directly related to topographic height, with green at the lower elevations, rising through yellow and tan, to white at the highest elevations. Image courtesy of NASA.
