Mount Merbabu
Encyclopedia
Mount Merbabu is a dormant stratovolcano
in Central Java
province on the Indonesia
n island of Java
. The name Merbabu could be loosely translated as 'Mountain of Ash' from the Javanese
combined words; Meru
means "mountain" and awu or abu means "ash".
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, the site of the village of Selo and highly fertile 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
. An unconfirmed eruption may have occurred in 1570.
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.
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.
An area of 57 km² at the mountain has been declared a national park in 2004.
Stratovolcano
A stratovolcano, also known as a composite volcano, is a tall, conical volcano built up by many layers of hardened lava, tephra, pumice, and volcanic ash. Unlike shield volcanoes, stratovolcanoes are characterized by a steep profile and periodic, explosive eruptions...

Fissure vent
A fissure vent, also known as a volcanic fissure or simply fissure, is a linear volcanic vent through which lava erupts, usually without any explosive activity. The vent is usually a few meters wide and may be many kilometers long. Fissure vents can cause large flood basalts and lava channels...

Lava refers both to molten rock expelled by a volcano during an eruption and the resulting rock after solidification and cooling. This molten rock is formed in the interior of some planets, including Earth, and some of their satellites. When first erupted from a volcanic vent, lava is a liquid at...
