Mount Merbabu (Indonesian: Gunung Merbabu) is a dormant stratovolcano in Central Java province on the Indonesian island of Java. Loosely translated, Gunung Merbabu could mean 'Mountain of Ash' from the Indonesian word babu. The active volcano Mount Merapi is directly adjacent on its south-east side, while the city of Salatiga is located on its northern foothills. A 1,500m high broad saddle lies between Merbabu and Merapi[1], the site of the village of Selo and highly fertile[citation needed] farming land.
There are two peaks; Syarif (3,119 m) and Kenteng Songo (3,145 m). Three U-shaped radial valleys extend from the Kenteng Songo summit in northwesterly, northeastly and southeastly directions.
Two known moderate eruptions occurred in 1560 and 1797. The 1797 event was rated 2: Explosive, on the Volcanic Explosivity Index.[2] An unconfirmed eruption may have occurred in 1570 [3].
Geologically recent eruptions originated from a North Northwest-South Southeast fissure system that cut across the summit and fed the large-volume lava flows from Kopeng and Kajor craters on the northern and southern flanks, respectively.[4]
Merbabu can be climbed from several routes originating from the town of Kopeng on the north east sideside, and also from Selo on the southern side. A climb from Kopeng to Kenteng Songo takes between 8 and 10 hours
