Types And Signs Of The Volcano Will Erupt

The eruption is the movement of magma that can reach the earth's surface through, impeccably crack then burst high into the air, which brings the material ash and rocks. eruptive events may lead to the emergence of larvae which is molten magma comes out slowly - land. will appear wide crater formed due to volcanic upper body come thrown because of the strong eruption, it is called a caldera.

Type volcano

• Volcanic cone (Strato) volcano tapered shape and cross-section has a lot of layers. examples Mount Merapi and Mount merbabu
• Volcanic headlands (Persian) is generally not high, but widened and ramps resembling a shield. mountain example Maona loa in Hawaiian archipelago.
• Volcano funnel (MAAR) has a type of volcano crater hole with a funnel-shaped crater walls are not too high. for example, is a mountain located in Lamongan East Java Indonesia.

As for the sign - a sign of a volcano will erupt are as follows:

• audible a voice rumbling of the volcano
• Temperatures around the crater rises
• It often happens smooth earthquake
• Animals down the mountain looking for a safe place.
• Plants around the crater wilt.

When the volcano erupted spend a lot of materials from the bowels of the mountain among others are as follows:

1. Material Gas (Ekshalas) chart gases emitted can be? Silfator gaseous sulfur, Fumaroles forms such as water vapor, Mofet, forming carbonic acid gas which is dangerous.
2. The molten material in the form of larvae, the magma melted off the slopes of the volcano, which is a mixture of hot lava magma with water so that it becomes mud and flows into all arah. Lahar Cold, the lava that has cooled and crushed by rain so it becomes mud.
3. Solid materials (Efflata) large rocks, lapilli a stone the size of a pebble, sand, dust, and ash.
