超级火山一般是指能够引发极大规模爆发,且火山喷发物总量大于1000立方千米的火山。超级火山的爆发可以瞬间改变地形、全球天气,甚至可能导致全球性的生命灾难。超级火山喷发时,火山灰中的含硫物质散布于空中,经过物理化学变化形成高浓度硫酸,可以导致大气中含有2000兆至4000兆吨硫酸,大致相当于目前全球每年所有工业含硫物质排放总量的25倍多,还可以使海水温度骤降6摄氏度左右,火山灰和喷出的气体还将进入大气层,造成全球性的火山冬天,破坏力极其可怕。
Super volcano generally refers to a volcano that can trigger a very large-scale eruption, and the volcano eruption total more than 1000 cubic kilometers. Super volcano eruptions can instantly change the terrain, the global weather and may even lead to a global catastrophe of life. Super volcanic eruption, volcanic ash in the sulfur-containing material scattered in the air, through physical and chemical changes to form a high concentration of sulfuric acid, can lead to the atmosphere contains 2000 to 4000 megatons of sulfuric acid, roughly equivalent to the current global annual total industrial sulfur emissions More than 25 times the amount of water can also make sea temperature plunged about 6 degrees Celsius, volcanic ash and gas will spurt into the atmosphere, resulting in a global volcano in winter, the destructive power is extremely scary.
