Batu Tara has been active since January 2007, with thermal anomalies and frequent low-level ash plumes at least through 24 November 2009 (BGVN 34:10). Between 24 November 2009 and 23 February 2010, the volcano was quiet, with the exception of an ash plume on 23 January. According to the Darwin Volcanic Ash Advisory Centre, the ash plume rose to an altitude of 1.5 km and drifted 25 km E.
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.
