Description: Aoba Volcano (Mt Manaro) is the dominant feature in this shaded-relief image of Ambae Island, part of the Vanuatu archipelago, which includes more than 80 islands in the South Pacific located about three-quarters of the way from Hawaii to Australia. Last active in 1996, the 1,496-meter (4,908-foot), Hawaiian-style, basaltic shield volcano has lakes within its summit caldera, or crater. The November-December eruption involved a vent at the center of Lake Voui (at left), which was formed approximately 425 years ago after an explosive eruption. |
