During 30 June-4 July observers at Batu Tara noted Strombolian eruptions of varying intensity at intervals ranging between 10 and 50 minutes. Three pyroclastic flows traveled as far as 200 m over the sea during a 16-hour period of elevated activity between 2 and 3 July.
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.
