Melting lava moves to the ground, with large amounts, fast speeds, wide-scale coverings, can destroy live objects, environmental variation for areas of ambient influences in 9: 00/4: 22 Southern region of volcanic formation is like tsunamis and volcanoes is one of the extremely dangerous natural phenomena and seriously affects people's lives. This is the mysterious phenomenon of Earth when still The activity of seismic and jelly shells continue to move on a melting mineral layer. Fire bag causes threat to tens of thousands of people around. Today about 500 volcanoes are operating on earth, and every year have 10 to 40 volcanic eruptions. Volcanic eruptions create dangerous impacts on the environment, climate and health of exposed people, and are related to the recession of economic and social conditions

And during the eruption process, before the volcano products on the ground sprayed on the ground, they would rub from the ground up, creating tremors that accompanied the bangs from small to large, May cause phenomena such as landslides, subsidence or land cracking. Fire bags start the eruption that changes topographic surfaces such as volcanic lava will rise, then form terrain forms like highland arches or lava coating. In addition, the eruption volcanic also seriously affects human habitats when volcanoes spray on the ground with a large amount of lava with fast speed, will destroy live objects. The earth's face is very hot, and goes deeply towards the Earth core (or the earth). With a depth of 20 miles (about 32 km) below the Earth surface, the temperature here is so hot that it can be fused almost all stones. In the heart of the Earth, the temperature is even more terrible, about 6,000 degrees C.Dung Nham "wipes" everything on the way of the wake up can erupt a huge amount of melting lava with gas Underground capacities, buried all life around the mountain mouth. I know, lava is hot stone flowing from the volcano during eruption. When erupting from volcanoes, lava in liquidity with a temperature of about 700 degrees C - 1,200 degrees C (1,300 degrees F to 2,200 degrees F). Although, the lava is quite viscous, higher than water about 100,000 times, it can flow on a long distance before peeling into a stone, due to its thixotropic and shear thinning characteristics
volcano. (Photo: usgs.gov) In particular, the dome-shaped lava is a type of circle, derived from the slow eruption of the viscous lava on a volcano. In the lava arches, it comes out of cracks and cracks, which can reach hundreds of meters and slow growth for months or years. Everything on the way of the moving lava line will be Take off, destroy, buried or burned by the extremely hot temperature of the lava. When the lava erupts below the glacier or flows on snow, melting water from tape and snow can spread across a large range. If the lava enters the waters or water into the lava pipes, water can Boil up fiercely and causes a basting rain on a large area. Metalist, created in a large vegetation, can be moved in the surface gaps and explodes when heated . The library lines are special, especially the lines of the dome shape, may collapse to form fast moving pyrolastic streams. Nung Nham flows out from the Kilaua volcano. (Photo: Daily Mail) Direct deaths because the lava flow is uncommon, because most of its flow is slow enough for humans to move, run out easily. However, death and injuries may occur when people approach near the lava stream they are moving forward or their withdrawal is prevented by other flows. In when the deaths of the lava flow Often due to related causes, including explosions when lava interacts with water, the collapse of an active lava plain area is formed where the lava enters a water area, suffocating due The accompanying poison, pyrolastic flow from a dome eruption ... the lava hot melt on the ground, with a large amount, fast speed, covered on a large scale, can destroy live objects, Variations environmental environment effects of volcanoes. At the same time, coating, damaging traffic construction works, irrigation ... as well as other assets created by humans. Also, it also causes forest fire, ecological environment changes, destruction, Renovation of biological resources in influence, can increase the sensitivity of flooding soil erosion, flash floods, landslides ...
