Based on analyses of satellite data, the Darwin VAAC reported an ash plume from Batu Tara on 15 June rising to an altitude of 2.1 km (7,000 ft) a.s.l. and drifting 55 km SW. During 16 June the plume was slightly lower, at 1.5 km (5,000 ft) a.s.l., extending 37 km NW.

Geologic Background. The small isolated island of Batu Tara in the Flores Sea about 50 km N of Lembata (fomerly Lomblen) Island contains a scarp on the eastern side similar to the Sciara del Fuoco of Italy's Stromboli volcano. Vegetation covers the flanks to within 50 m of the summit. Batu Tara lies north of the main volcanic arc and is noted for its potassic leucite-bearing basanitic and tephritic rocks. The first historical eruption, during 1847-52, produced explosions and a lava flow.
