Lewotobi

Stratovulcano · Indonesia · 1703 m

Lewotobi Lakilaki (left) and Lewotobi Perempuan (right) rise above forests on their western flanks. They were constructed along a NW-SE-trending line. Both volcanoes have erupted during historical time but Lakilaki has been more active.

Sintesi geologica

The Lewotobi edifice in eastern Flores Island is composed of the two adjacent Lewotobi Laki-laki and Lewotobi Perempuan stratovolcanoes (the "husband and wife"). Their summits are less than 2 km apart along a NW-SE line. The conical Laki-laki to the NW has been frequently active during the 19th and 20th centuries, while the taller and broader Perempuan has had observed eruptions in 1921 and 1935. Small lava domes have grown during the 20th century in both of the summit craters, which are open to the north. A prominent cone, Iliwokar, occurs on the E flank of Perampuan.
