Super volcano is a volcano that can trigger a large-scale outbreak. Although volcanic eruptions and surrender of magma and rock in areas over 240 cubic kilometers (1000 cubic kilometers) are considered to be super volcanoes, although the scale of the outburst is not rigorously defined. These large-scale outbreaks make typical volcanic eruptions become pediatric, like the contrast between static electricity and lightning.
American Yellowstone National Park is the world famous super volcano. Its last outbreak was in the 64,000 years ago, and the ashes covered California to Minnesota. If the Yellowstone Park's super volcano erupted again, the ashes will be sprayed into the roofs of neighboring houses. Then the loss will undoubtedly be huge: "Thousands of people will die due to the direct eruption and the loss of volcanic debris (lava)." Dust in the air can cause difficulty breathing, so it will kill more People, in addition to super volcano is also a serious impact on the global temperature.
Volcanic eruption index (VEI) to 0-8 to assess the power of volcanic eruptions. Known to have more than 40 volcanic eruptions in the world, the largest scale is located in the southern province of Parana, Brazil, the size of the largest 3.5 times the size of the Yellowstone volcano, in addition to Parana also occurred 9 times 8 eruption, Out of 49590 cubic kilometers of volcanic material. Super volcanic eruptions can have catastrophic consequences, they can destroy the whole earth. In the worst case, the super volcano will spray thousands of cubic kilometers of magma and volcanic ash in just a few days or months. Floating ash in the atmosphere can block the sun's rays and heat and last for years or even decades.
It seems that the super volcanic eruption is not just the destruction of a city so simple, the whole earth may be followed by the demise. Almost all volcanic experts agree that if today's earth erupted on this planet, mankind would be able to withstand such blows.
