(*only for information);
Name:
Mt. Arjuna-Welirang Complex ;
Note:
Mount Arjuno is adjacent to Mount Welirang, Mount ‘Kembar I’, and Mount ‘Kembar II’. The summit of Mount Arjuno lies on one ridge equal to the peak of Welirang mountain, so the complex is often referred to as Arjuno-Welirang. The Arjuno-Welirang complex itself is located in two older volcanoes, Mount Ringgit in the east and Mount Lincing in the south. Fumarole areas with sulfur reserves are found in a number of these mountainous locations, such as at the peak of Mount Welirang, the peak of the ‘Kembar II’, and on a number of hiking trails…

Topology & Geology;
The Arjuno-Welirang Volcano Complex has several cones at its peak: the Arjuno Mountain Cone (3339 m above sea level, the oldest cone), the ‘2900 m asl) cone, the’ Kembar II ‘(3126 m above sea level) The cone of ‘Kembar I’ (3030 m above sea level), and the ‘Welirang’ Mount Cone (3156 m above sea level). The cones are formed by the displacement of the eruption point which forms the straightly south-northwest direction and is controlled by a normal faults. In addition to these cones are also some parasitic cones which are the result of a side eruption on the body of Kompkeks Gunung Arjuno-Welirang. The parasitic cone is Mount Ringgit (2477 m asl.) In the northeast, Mount ‘Pundak’ (1544 m asl) and ‘Butak’ Mountain (1207 m asl) in the north, and two other cones namely Mount Wadon and Mount Princi in the eastern body.
Arjuno-Welirang Arjuno Complex rocks are produced by three central eruptions from Mount Arjuno Tua, Gunung Arjuno Muda and Mount Welirang in the form of lava flows, pyroclastic flows, pyroclastic and lava flows that spread to the north and west (Vulcanology News, Special Edition, 1992, Mount Arjuno-Welirang).
