Based on analyses of satellite imagery, the Darwin VAAC reported that during 4-5 and 9-12 June ash plumes from Batu Tara rose to altitudes of 1.8-3 km (6,000-10,000 ft) a.s.l. and drifted 37-93 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.
