Based on information from CVGHM and satellite imagery, the Darwin VAAC reported that continuous diffuse plumes rose to 1.5 km (5,000 ft) a.s.l. and drifted mainly SE during 21-27 March.

14 March-20 March 2007

Based on satellite imagery and CVGHM, the Darwin VAAC reported that during 14-16 and 19-20 March emissions from Batu Tara produced diffuse plumes that drifted NE, SE, and E. Plumes rose to 1.2 km (3,900 ft) a.s.l. on 19 and 20 March.

7 March-13 March 2007

Based on satellite imagery, the Darwin VAAC reported that an ash cloud from Batu Tara reached an altitude of 4.3 km (14,000 ft) a.s.l. on 13 March and drifted N. The plume was identified on 14 March drifting NE.

The small isolated island of Batu Tara in the Flores Sea about 50 km north 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 of Batu Tara to within 50 m of the 748-m-high 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 from Batu Tara, during 1847-52, produced explosions and a lava flow.
