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.

Background

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.

Remark:

Our list of volcanic eruptions closely follows the database of eruptions of the Smithsonian's Global Volcanism Project (GVP), the internationally most recognized data source for volcanic eruptions, but also includes significant eruptive episodes or related volcano events. "Volcanic eruptions" are usually to be understood as sequences of individual eruptive episodes that can follow each other, or even overlap (if several vents are involved), and can last many years, decades or even longer. For example, the current activity of Stromboli volcano is understood as a single eruption that has been ongoing since 1934.
