Sangeang Api

Vulcano complesso · Indonesia · 1912 m

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

Sintesi geologica

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, Doro Api and 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 eruptions have been recorded since 1512, most of them during in the 20th century.
