Sangeang Api volcano is one of the most active in the Lesser Sunda Islands. It forms a small 13 km wide island off the NE coast of Sumbawa. Sangeang Api Volcano consists of 2 overlapping cones: active Doro Api (1949 m) and the older cone and Doro Mantoi (1795 m).
Sangeang Api's eruptions are often effusive with lava flows accompanying strombolian activity following an initial explosive phase.
The two large trachybasaltic-to-tranchyandesitic volcanic cones of Doro Api and Doro Mantoi were constructed in the center and on the eastern rim of an older, now almost buried caldera. Flank eruptions have built flank cones on the south side of Doro Mantoi and near the northern coast.
