Wetar Volcano is an isolated volcanic island on the north of Wetar island in the Banda Sea, Indonesia.
Although this volcano is only 282 m above sea level, it is thought to be the highest volcano in the Indonesian volcanic region. Based on the results of echosounding around the area, it shows that this volcano grows as high as 5000 m from the sea floor. During its cone growth, three traces of a large avalanche were found, i.e., on the northwestern slope which left a wide field of avalanches. 80 m starting below the sea level line to exceed the 200 m depth line; the second on the eastern slope leaving the avalanche field from the upper slope to below the 200 m and third depth line on the eastern slope, breaking down the crater lip and leaving the avalanche field to the 200 m depth line to open the crater to the east, thick landslide. 50 m which can be seen from the contact area of the lava and the pyroclastics above…

Topology & Geology;
Verbeek (1908) analyzed two examples of andesite lava taken from the east coast, consisting of fine-grained andesite pyroxene with phenocryst plagioclase, hipersten, augite, biotite and olivine containing picotite, magnetite and apatite and the basic period of pyroxene microlite, plagioclase, and ore minerals colorless to brownish.
Kuenen (1935) took several andesite samples from the west coast of bright gray to dark or reddish, consisting of pyroxene basalt, generally a shaft with white and dark phenocrysts several millimeters in diameter. One example is olivine while the other is only in the form of inclusion along with plagioclase, pyroxene and ore minerals. Sometimes hypersten is more dominant than augite and biotite is generally a side mineral…
