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.

Geological Summary. The small isolated island of Batu Tara in the Flores Sea ~50 km N of Lembata (fomerly Lomblen) Island and the main volcanic arc. A scarp on the eastern side reaches the sea, and vegetation covers the other flanks to within 50 m of the summit. This volcano is noted for its potassic leucite-bearing basanitic and tephritic rocks. The first recorded eruption, during 1847-52, produced explosions and a lava flow.
