Batu Tara

Tara, Batu

Stratovolcano · Indonesia · 633m

Batu Tara, seen here from the SE, is a small 3-km-wide island that is the summit of a large stratovolcano that rises from the Flores Sea about 50 km north of Lembata (formerly Lomblen) Island. The summit of the volcano is cut by a scarp on the eastern side (right) that is similar to the Sciara del Fuoco on Italy's Stromboli Island. Only a single historical eruption, during the mid-19th century, is known from Batu Tara.

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.
