Mount Merbabu (Indonesian:Gunung Merbabu) is adormantstratovolcano inCentral Java province on theIndonesian island ofJava. The nameMerbabu could be loosely translated as 'Mountain of Ash' from theJavanese combined words;Meru means "mountain" andawu orabu means "ash".
The active volcanoMount Merapi is directly adjacent on its southeast side, while the city ofSalatiga is located on its northern foothills. A 1,500m high broad saddle lies between Merbabu and Merapi,[2] the site of the village ofSelo, Java, and highly fertile[3][4] farming land.
There are two peaks;Syarif (3,119 m) andKenteng Songo (3,145 m). Three U-shaped radial valleys extend from the Kenteng Songo summit in northwesterly, northeasterly, and southeasterly directions.

Two known moderate eruptions occurred in 1560 and 1797. The 1797 event was rated2: Explosive, on thevolcanic explosivity index.[5] An unconfirmed eruption may have occurred in 1570.[6]
Geologically recent eruptions originated from a North Northwest-South Southeastfissure system that cut across the summit and fed the large-volumelava flows from Kopeng and Kajor craters on the northern and southern flanks, respectively.[2]
Merbabu can be climbed from several routes originating from the town ofKopeng on the northeast side, and also from Selo on the southern side. A climb from Kopeng to Kenteng Songo takes between 8 and 10 hours.[citation needed]
An area of 57 square kilometres (22 sq mi) at the mountain has been declared anational park in 2004.[7]
