Geological Summary. The small isolated island of Batu Tara is located in the Flores Sea ~50 km N of Lembata (formerly 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.
