Sangeang Api

Sangeang Api volcano, one of the most active in the Lesser Sunda Islands, forms a small 13-km-wide island off the NE coast of Sumbawa Island. Two large trachybasaltic-to-tranchyandesitic volcanic cones, 1949-m-high Doro Api and 1795-m-high Doro Mantoi, were constructed in the center and on the eastern rim, respectively, of an older, largely obscured caldera. Flank vents occur on the south side of Doro Mantoi and near the northern coast. Intermittent historical eruptions have been recorded since 1512, most of them during in the 20th century.

Sangeang Api is a small volcanic island off the NE coast of Sumbawa Island. Two large volcanic cones, Doro Api in the center and Doro Mantoi on the right, were constructed within and on the south rim of a largely obscured caldera. Intermittent eruptions have been recorded since 1512, but the volcano has been frequently active in the 20th century.
