PROCESS OF volcano eruption

Volcanic eruption, magma caused by sediment in the bowels of the earth is pushed out by high-pressure gas. Of such eruptions of the volcano is formed. Eruptions of ash and rock that brought loud burst with radius as far as 18 km or more, being able to overwhelm the lava as far as 90 km radius. Volcanic eruptions can cause casualties and huge property to thousands of kilometers away and even bias affects the climate on earth is round. The results of volcanic eruptions (source: MPBI)

volcanic gas
Lava and flow of sand and hot rock
Ash eruption
Hot clouds (pyroclastic)
Volcanic gases are gases released during volcanic eruptions that released carbon monoxide, among others, (CO), Carbondioksida (CO2), Hydrogen Sulfide (H2S), sulfur dioxide (SO2) and nitrogen (NO2) are dangerous to humans.

Lava is magma that high-temperature fluid flow to the surface through a volcanic crater. Liquid lava can flow away from the source follows the river or the valley while the thick lava flows not far from the source. Lava is one danger to society tingla on the slopes of the volcano. Is a flood of lava on the slopes Bandang consisting of a mixture of clay-sized material until volcanic boulders. Known as the lava eruptions and lava rain. Lava eruptions occur when a volcano that has erupted crater lake, so the lake water mixes with the hot material of the eruption, while the rain lava eruptions occur due to material mixing with rain water around the peak.
Hot clouds can form pyroclastic flows, pyroclastic blast and pyroclastic fall-out. Thermal cloud is a cloud of material flow eruption of hot, flowing down and finally settled in and around the river from the valley. Blowing hot cloud is a cloud of hot material a small eruption, blown by the wind speed reaches 90 km / h. Dropping the hot cloud is a cloud of hot material large and small eruption that was brought up by the power of a large eruption. Large material will fall around the peak, while the fine would fall in the tens, hundreds or even thousands of miles from the summit because of the influence of wind gusts. Hot clouds can cause burns to exposed body parts such as head, arms, neck or legs and also to not cause shortness of breath.

Volcanic ash is very fine material. Because the effects of wind can be felt hundreds of kilometers away. The impact of ash eruptions
Respiratory problems, vision problems, pollution of water sources, causing an electrical storm, disrupting work and motor vehicle engines, damaging the roof, damaging fields, damaging infrastructure. Preparations for Volcano Eruptions
identify local areas in determining a safe place to evacuate
disaster planning
prepare for evacuation if necessary
prepare the basic needs (food, clothing protective equipment)

In the event of Volcano Eruption
Avoid areas prone to disasters such as mountain slopes, canyons and lava flow area
In the open, protect themselves from ash and pyroclastic eruption
Prepare yourself for the possibility of follow-up disaster
Wear clothing that can protect the body, such as long sleeves, long pants, hats and other
Use eye protection such as goggles or other
Do not wear contact lenses
Wear a mask or cloth over the mouth and nose
Current pyroclastic fall try to cover her face with both hands.
In the aftermath of the Volcano Eruption
stay away from areas affected by ash falls
Clean the roof of Abu heap, because the weight can damage the ataun collapsed the roof of the building
Avoid driving in areas affected by ash fall because it can damage the engine, brakes, gears up to ignition.
