Based on analyses of satellite imagery and wind data, the Darwin VAAC reported that on 6 June an ash plume from Batu Tara rose to an altitude of 2.1 km (7,000 ft) a.s.l. and drifted 150 km NW. During 7-9 June ash plumes rose to an altitude of 2.1 km (7,000 ft) a.s.l. and drifted over 35 km NW and W.

Geological Summary. 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.
