End of the real world: when global 1500 volcanoes eruption ...-volcanoes, end of the world-IT information
According to the United Kingdom reported the daily mail, at present, the scientists said, if the world's 1500 potentially active volcanoes and eruptions, causing a devastating disaster to an end. Pyroclastic flow up to 1000 degrees Celsius temperature, velocity 724 kilometers per hour, global temperature is going to drop, resulting in heavy rain, damaging crops. Volcanic ash cloud will spread to thousands of kilometers, the effects of vehicle engine starting, building sinks, it is ash inhalation will cause health problems. Meanwhile, volcanic ash blotted out the Sun's rays, cause calcium deficiency in people, the Blues.
Except the bottom continuous volcanic belt in the world, about 500 volcanoes have erupted, however they did not do erupt. United Kingdom Bristol University volcano expert Matthew Watson (Matthew Watson) said: "are two different types of volcanic eruptions, the first is made of lava flows and gas; the second is manufacture of volcanic dust and gas. Both active difference is mainly controlled by the viscosity of magma. ”
Higher viscosity of the magma would be difficult to release gases, lava burst is likely to occur, although volcanic eruption types there is a big difference, but if all volcanoes and eruptions on Earth, will bring devastating in many ways.
Recently from the eruption point residents first affected, not only the threat of lava flows, will also release a lot of dust clouds. Pyroclastic flows are fast-moving flow of rock, dust, and gas is very hot, the temperature can be up to 1000 degrees Celsius. People driving or running cannot outrun a pyroclastic flow rate, which can reach 724 kilometers per hour. In addition, pyroclastic flow will also destroy the volcano region 160 kilometers away, lives near the Volcano area residents suffered the most serious.
Volcano destroyed neighborhood is only a start, volcano releases ash into the sky, spreading to thousands of kilometres away. Dr Watson said the volcanic dust is very troublesome, it contains tiny crystals and rock debris. In addition to the potential impacts of volcanic ash engine, will also damage buildings and ash accumulated on buildings, gradually leading to building base subsidence.
Inhaling volcanic ash dust on the lungs, causing serious injury, which lead to silicosis, and the body's natural immune system damage, secondary health problems occur. In addition, the volcanic dust not only damage vehicle engines, people must wear masks when they go out, space communication will also be subject to interference, volcanic dust cloud could interfere with satellite signal and block radio waves are transmitted.
Volcanic eruption will result in long-term climate change, dust ash and gases into the atmosphere, would be to reduce global temperatures. Dr Watson said: "the volcano releasing sulphur dioxide is converted into aerosol particles that can reflect the Sun's rays into space, thereby significantly lowering the Earth's temperature, ice age climate potentially occur. ”
真正的世界末日：当全球1500座火山同时喷发… - 火山,世界末日 - IT资讯
据英国每日邮报报道，目前，科学家表示，如果全球1500座潜在的活火山同时喷发，将酿成一场毁灭性的末日灾难。火山碎屑流达到1000摄氏度高温，传播速度每小时724公里，全球气温将下降，导致大暴雨，毁坏农作物。火山灰将传播至数千公里，影响交通工具的发动机启动，使建筑物下沉，人们吸入火山灰将带来健康问题。同时，火山灰遮蔽了太阳光线，导致人们出现缺钙症，心情抑郁。
全球除了海底有连续的火山带，大约有500座火山曾喷发过，然而它们并未同时喷发。英国布里斯托大学火山专家马修-沃特森(Matthew Watson)博士说：“火山喷发分为两种不同类型，第一种是制造熔岩流和大量气体；第二种是制造火山灰尘和气体。两者活跃性的差异主要是受到岩浆黏度控制。”
黏度越高的岩浆就很难释放气体，很有可能会出现岩浆爆发，尽管火山喷发类型存在很大的差异，但是如果地球上所有火山同时喷发，在许多方面将带来毁灭性灾难。
距离火山喷发点最近的居民首先遭受影响，不仅有火山岩浆流的威胁，还会释放大量灰尘云。火山碎屑流是快速移动的岩石、灰尘和气体流，非常炽热，温度可达到1000摄氏度。人们开车或者奔跑不可能超越火山碎屑流的速度，后者可达到每小时724公里。此外，火山碎屑流还将摧毁火山喷发点160公里之外的区域，生活在火山邻近区域的居民遭受影响最严重。
对火山邻近区域的摧毁仅是一个开始，火山喷发将释放大量火山灰进入天空，传播至数千公里之外。沃特森博士称，火山灰尘是非常令人棘手的，它包含着微小的晶体和岩石碎屑。火山灰除了潜在影响发动机，还将破坏建筑物，火山灰将堆积在建筑物上，逐渐导致建筑底基下沉。
吸入火山灰尘还将对肺部构成严重损伤，其中导致硅肺病，同时使人体免疫系统过度损伤，出现二次健康问题。此外，火山灰尘不仅损坏交通工具发动机，人们外出时必须佩戴着口罩，太空通讯也将遭受干扰，火山灰尘云会干扰卫星信号，阻挡无线电波传送。
火山喷发将导致长期性地球气候变化，大量火山灰尘和气体进入大气层，将全球性地降低气温。沃特森博士说：“火山喷射释放的二氧化硫将转变成为气溶胶微粒，可以反射太阳光线至太空，从而显著地降低地球温度，潜在地出现冰河时代的气候状况。”
