(*only for information);
Mt. Slamet; Mt Agung [referred to as Mt Agung in a Sundanese manuscript of the adventure of Bujangga Manik is Mount Slamet (J. Noorduyn)]
The Dutch historian J. Noorduyn theorizes that the name “Slamet” is relatively new, ie after the entry of Islam into Java (the word is an Arabic loan). He argues that the so-called Gunung Agung in the Sundanese manuscript of the adventure of Bujangga Manik is Mount Slamet, based on the exposure of the mentioned location
Crater IV is the last crater that is still active until now, and last active until the level of standby medio-2009.Mount Slamet is formed due to Indo-Australian Plate subduction on the Eurasian Plate in the south of Java Island. Cracks in the plates open the lava path to the surface. Records of eruptions are known since the 19th century. The mountain is active and often has small-scale eruptions.This mountain has a forest area of Dipterocarp Hill, Upper Dipterocarp forest, Montana forest, and Ericaceous Forest or mountain forest.

Elevation (meters above sea level);
3.428 m (11.247 ft)
Type of eruption;
Based on the historical record of the eruption, in general the eruption of Mount Slamet is an ash eruption accompanied bursts of sekoria and incandescent, occasionally issued a lava incandescent. The eruption lasted several days, in extraordinary circumstances reaching a few weeks.

In the event of a major eruption, such as the eruption of Mount Agung (1962), Mount Galunggung (1982) or Mount Colo (1983), the main danger of Mount Slamet eruption or primary hazard (direct hazard due to eruption) is a hot clouds slide, pyroclastic flares (volcanic bomb , lapilli, sand and ash) and possibly lava flows. The secondary hazard (the indirect danger of eruption) is the rain lava that occurs after the eruption when it rains heavily around the peak.

The far-reaching distribution of pyroclastic falls, depending on the height of the blast and the wind blowing at the time of the eruption, especially the spread of ash and sand rain. Eruption Period. The eruption of Mount Slamet repeatedly in the tempo, lasting the longest to several weeks (less than a month).

The shortest break period between two eruptions lk. 1 year and longest 53 years. For lk break period. 1 year may still be a single phase of eruption or follow-up activity.

Topology & Geology;
The sedimentary eruption of Mount Slamet from old to young was all quartered, covering tertiary-aged sedimentary rocks. Some of the eruptions of G. Slamet include 5 districts with an area of ​​1500 km2 consisting of precipitated Piroklastika droppings, lava flows, lava, hot clouds and surface deposits of Alluvial and Flluvial. Generally, the lava deposits found in Mount Slamet are Andesitic.

Geological structure that develops in the area of ​​Mount Slamet and surrounding areas, generally in the form of normal faults are commonly found in the group Slamet Tua. Traces of this fault in the field are found in the form of Breksiasi, scratch fault line, destruction zone, alignment of hills and valleys, straight and steep escape and sharp contact between rock units. Based on the criteria mentioned above, the geological structure that developed in Mount Slamet can be divided into 3 pieces of fault structure are: Normal Fault Jegjeg, Normal Fault Marinating, Normal Fault Mengger, Graben Guci, Normal Si Jambang Fault, Normal Fault Buntu, Normal Fault Mount Gratamba, Normal Karanggondang Fault, Normal Fault Kubangan, Normal Fault of Kalipagu and Normal Fault Gangs.
