TYPES OF DEPRESSION volcanic
Depression is the morphology of the volcanic Volkan which generally form the basin. Based on the filler material is divided into seven volcanic depression:
1. crater
The crater is the depression formed by volcanic eruptions with a maximum diameter of 1.5 km, and not occupied by any material other than the eruption.
2. crater lake
Crater is a crater lake filling with rain.
3. caldera
Volcanic caldera that is depression, not necessarily by the formation of the eruption, but was preceded by subsidence in the complex Volkan, measuring more than 1.5 km. Usually the caldera formed by the eruption and lava terhembusnya hole, then followed by the avalanche crater wall.
4. Dent tectonic volcanics (Major Vulcano-Tectonic Depression)
An indentation is very large and elongated shape are influenced by tectonic and volcanic processes.
5. Lurah volcano (Volcanic Graben)
Lurah volcano is a straight-walled structures that collapse, which occurred dibagian peak cone volcano slopes.
6. Gap volcano (Volcanic Fissure Through)
Form of elongated grooves on the body due pencelahan volcano. Pelengseran Pencelahan occurs because one side of the slab due to stress or pressure of the magma breaking through the cone material excessive burden which rested on a weak base layer.
7. Pseudo volcanics (Pseudo Volcan)
Morphology similar to volcanic cones, which comprise material derived from adjacent Volkan.
