Morphology of the volcano

Morphology of the volcano can be divided into 3 zones:

1. Zone eruption center (top)
The top of the volcanic sediment facies is characterized by central, located approximately 2 km from the pit crater. In general, sloped-angle 35̊ 42̊ and composed of loose material.
The characteristics of the central zone eruption:
a. Many radial dike or sill
b. The existence of the plug (plug) and crumble brecia
c. The existence of zone hidotermal
d. Nature of coarse piroklastiknya
e. Morphology of the dome shape with a hole eruption

2. Zone paroksimal (body part)
Body parts are characterized by volcanic facies paroksimal, within 5-15 km from the center hole crater. With the slope of the topography is between 10̊-20̊.
Paroksimal zone characteristics:
a. Pyroclastic material is rather oriented.
b. There is a weathered zone on the lava and pyroclastic materials are characterized by thin soils.
c. Common parasitic cone (dome parasites)
d. Many found ignimbrite and welded tuff
e. Sill and dike is still there.

3. Zone distal (foot slope)
The foot of the slopes of the volcano is characterized by distal facies ramps with a slope of less than 5̊.
Characteristics:
1. Epiklastik pyroclastic material and form a layer of sediment in the form of clay to gravel which has been generally smooth.
2. The existence of the coating bead turn ugly with a granular layer is better.
3. The existence of lava flows down the valley.
