地質学的概要
The Arjuno and Welirang volcanoes anchor the SE and NW ends, respectively, of a 6-km-long line of volcanic cones and craters. The complex overlies most of the Gunung Ringgit edifice, whose summit is about 3 km NE from the main ridge. Pyroclastic cones are located on the north flank of Gunung Welirang and along an E-W line cutting across the southern side of Gunung Arjuno that extends to the lower SE flank. Fumarolic areas with sulfur deposition occur at several locations on Welirang.
Wikipedia の要約
英語版の要約Mount Arjuno-Welirang is a stratovolcano in the province of East Java in Java, Indonesia. Mount Arjuno-Welirang lies about 50 kilometers south of Surabaya, and 20 kilometers north of Malang. It is a twin volcano, with the 'twins' being Arjuno and Welirang. There is at least one other stratovolcano in the area, and around 10 pyroclastic cones nearby. They are located in a 6 km line between Arjuno and Welirang. The Arjuno-Welirang volcanic complex itself lies in the older two volcanoes, Mount Ringgit to the east and Mount Linting to the south. The summit lacks vegetation. Fumarolic areas with sulfur deposits are found in several locations in Welirang.
