Volcano eruption
Volcano eruption is an event that occurred due to sediment in the bowels of the earth's magma is pushed out by high-pressure gas.Magma is liquid filament contained in a layer of earth with a very high temperature, which is estimated at more than 1,000 ° C. The liquid magma out of the earth is called lava. The temperature of lava issued could reach 700-1200 ° C. Volcanic eruptions that brought rock and ash can be sprayed as far as a radius of 18 km or more, while the lava to flood so far 90 km radius.
The volcano will erupt can be known through a few signs, among other
* The temperature in the vicinity of the mountain ride.
* Eyes water into dry
* Often rumbling noise, sometimes accompanied by vibration (earthquake)
* Plants wilt around the mountain
* Animals migrate around the mountain
Here is the result of volcanic eruptions, among others:
Volcanic Gas
Gases emitted by volcanoes erupting at the time. These gases include Carbon monoxide (CO), Carbon Dioxide (CO2), Hydrogen sulfide (H2S), sulfur dioxide (S02) and Nitrogen (NO2) which can membahayahan humans.
Lava and flow of sand and hot rocks
Lava is magma with high temperature fluid flowing from the Earth to the surface through the crater. Thin lava flows followed the river flow while the viscous lava will freeze close to the source. Lava that freezes to form a variety of rocks.
Lava
Lava is lava that has been mixed with rocks, water, and other materials. Lava is very dangerous for the residents on the slopes of a volcano.
Ash eruption
That is a very fine material that sprayed into the air during the eruption. Since it is very smooth, the ash can be carried by wind and felt hundreds of miles away.
Cloud heat
That is the result of the eruption that flows like clouds rolling. In the rolls have a hot incandescent rocks and volcanic material solid with a temperature greater than 600 ° C. Cloud heat can cause burns on exposed body like head, arm, neck or legs and also can cause shortness of breath.
Not all volcanoes often erupt. Volcanoes are often called active volcanoes erupting.
