Current events, volcanic eruptions still occur gradually. Even once the damage is at the core of thousands of deaths. In terms of population loss may not be as severe as other natural disasters, but in terms of impact on the environment, including changes in the geographic and natural disasters of this kind must be regarded as particularly appalling disaster
neighboring Indonesia. Our geography are the many islands of violent volcanic eruption ever happens at least three times
on approximately seven thousand, five thousand years ago a volcano Toba. Sumatra Indonesia explosion caused a giant rocks and ashes spread over the world, and obscured the sun. Finally, there is the presumption that such events cause a new ice age, the world was
1815 volcanic tambourines Hunt (Tambora) in Indonesia exploded. The eruption that made the ground shake and a loud clamor to go beyond 850 kilometers eruption that cause dust and debris, dust covers an enormous world until the world that year without summer. After more than 150 years later, scientists have additional information that the explosion of tambourines hunt was the most violent volcanic eruption in thousands of years. Even the eruption of Mount Vesuvius (visuvius) caused a lava flooding over the people as well as in Italy, or even a volcanic eruption on the island of San check (krakatoa) Indonesia in 1883 caused the noise. As to 4828 kilometers (three miles), caused a tsunami height of about 100 feet and the deaths of more than 3.5 billion population still can not be compared to the intensity of the eruption of Mount Tambo hunt. Scientists believe volcanic activity tambourines violent predators equivalent to the atomic bomb the United States dropped on Hiroshima enter the city. Japan In the time of World War II, about 60,000 children have a blast together. It is horrors of the volcano eruption in Indonesia volcanic landscape formed by http://vulcan.wr.usgs.gov causes volcanoes. And types of volcanoes as Earth's outer layers of Earth's space, not flat at the top crust on a stone when exposed to heat emitted from the Earth's core into a molten rock magma called magma (magma. the crust is called magma when it is pushed into the Earth's atmosphere are called lava) and when the heat from Earth's core, much will flow sequences Just like the water in check. Boil water that runs around the pot, along with sending smoke rising from the volcano vents, too, and eventually squirts out of the crevices of the plates typically caused by volcanic activity about 95 percent. The movement of tectonic plates overlap, known as tectonic subduction zone of technical terms that we are a solid rock. A thickness of approximately 40-60 kilometers Earth is a disc does not include homogeneous throughout the world. Earth's crust is divided into two categories based on the geographic Oceanic plate tectonic plates beneath the ocean with Continental plate or a continental plate, which appeared on the ground. So when the heat from Earth's core, it makes the earth plate movements throughout the world, we estimate that the plate is moving about 10 centimeters per year. When two plates collide, moves to make the world a piece of sheet, plate, duck into the world to another disc. Disc burrow down into the earth's crust that has a high heat, so the heat is trying to push to the outside. The nature of the plates overlap each other, is what we called a subduction zone volcanoes often occur along this subduction zone.
