How The Volcano Erupted
During its life time, volcanoes have conditions or conditions that are constantly changing over time, sometimes entering sleeping conditions where a volcano does not show any activity at all for tens to hundreds of years. However, in one condition the mountain will reactivate and erupt with terrible as happened to Sinabung mountain, North Sumatera which last erupted in year 1600an and in year 2010 active again and finally erupted in year 2013 until now its eruption activity still going on. Meanwhile, for volcanic eruption is a volcanic activity that is often called the term erupsi. Can be said almost all volcanic eruption activity is always associated with the zone of active kegempaan, this occurs due to the relationship between plate boundaries that have a very high pressure and temperature of more than 1000 degrees Celsius so that it can melt the surrounding rock material and become Magma.
Magma collects in magma located under the volcano, when the magma chamber is full, then magma pushed out of the volcano. Magma that has come out is called lava that has a temperature of 700 to 1200 degrees Celsius. When it erupts, a volcano can throw a variety of materials up to tens of kilometers away, not only that, heat and toxic gas cloud is also often a serious threat to people who live not far from the eruption. The volcanic eruption is one of many natural disasters that cause a lot of damage with huge losses because it destroys the residential and agricultural areas of the population, not to mention other impacts such as air pollution by beracum gas and trigger the cause of cold lava flood that can damage public infrastructure.
Here is an explanation of the causes of erupting volcanoes:
1. Increased volcanic earthquake
2. Crater Temperature Increases Significantly
3. The occurrence of Mountain Body Deformation
4. The Plates of the Plotted Earth Plate
5. Due to Very High Pressure
Volcano marks will erupt
a. Temperatures around the Mountain Rise
Especially can be felt by the people who live on the slopes or the foot of the mountain. The cause is because the activity of magma is increasing so gathered near the surface of the earth, so that the heat temperature of the magma is propagating to affect the layer of soil there exist throughout the body of the mountain.
b. Air Dry Eyes
This sign is actually still related to the previous point, because the magma pushed up so that the distance between the magma and the soil layer becomes closer, resulting in ground water evaporate and dry, because at certain layers in the soil the temperature becomes very hot so that drain the springs.
c. Plants Around Mount Withered
Because the heat of the soil temperature increases significantly, many plants wither. The effect is worse than withering because of the dry season.
d. Wild Animals Down the Mountain
One sign that is often encountered residents are many animals or wild animals that previously rarely seen down to the settlement of people who are at the foot of the mountain. This happens because animals feel uncomfortable with the rising temperatures occurring near the mountain peaks where their native habitat is.
e. Often Sound Noise
This incident indicates an increase in magma activity in the abdomen of the mountain as well as evidence that the higher the pressure so that not infrequently rumbling accompanied by the release of gas and volcanic ash.
