Based on analyses of satellite imagery and wind data, the Darwin VAAC reported that during 4-7 June ash plumes from Sangeang Api rose to an altitude of 3 km (10,000 ft) a.s.l. and drifted 45-110 km W and NW.

Geologic Background. 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 historical eruptions have been recorded since 1512, most of them during in the 20th century.
