What If All Volcanoes Erupted ?


What If All Volcanoes Erupted
Whether its molten molten lava crawls into the sea, or clouds of ash pour into the sky, the sight of the volcano erupts in itself a feeling of awe and wonder. What if 1,500 volcano exploded at once, how would it look ?! 1500 is the number of volcanoes active on the Earth's surface, plus an unknown number of hidden volcanoes under the ocean surface. Every day, shoots between twenty and thirty volcanoes lava somewhere on this simple. But scientists believe that the probability of eruption of all the volcanoes in the Earth together is a small possibility is almost nonexistent. But, what if it happened? Will the earth survive and remain as we know it? The answer to this question, is probably not. According to geologist Parv Sethi of Radford University in Virginia, the United States, volcanoes on the Earth's surface alone would have triggered a series of successive environmental impacts in a domino-like fashion, and the result would be much worse than nuclear winter. "It will be so bad that I do not wish to survive and stay on the ground in that case." The two biggest threats when volcanoes erupt on Earth are volcanic ash and gas from volcanoes. Although the blasts and lava eruptions will have a fatal impact on people living nearby, the death toll will be small compared to deaths from climate change following volcanic eruptions.

The Heat

Volcanic eruptions produce carbon dioxide , which can contribute to balancing with the global cooling effect of ash and particles in the stratosphere. But Parv Sethi wonders whether the eruption of 1,500 volcano together will engulf the entire earth system, "It seems like we've turned the key to the top of the stove." The question is, will this change the composition of the atmosphere to the extent that the atmosphere is poisoned with carbon dioxide "Let's be clear, we will be both." He adds that black mud sheets, a type of marine rock, indicate the occurrence of similar disasters in the history of the earth. City has studied these Cretaceous rocks. Rock records show that levels of carbon dioxide rose significantly in the Cretaceous period, resulting in the loss of marine life in some parts of the ocean and the disruption of sea currents. Scientists believe that levels of carbon dioxide in the late Cretaceous period, about 90 million years ago, were 2.5 times their levels today
Drowning in the dark
Parv Sethi predicts that a thick layer of ash will engulf the earth, and the sun will be completely obscured. "The planet will plunge into total darkness, which will stop photosynthesis, damage the plants, the vegetation death will cause the temperature to fall, and the ash will remain in the atmosphere for the next 10 years," he said. Although many of the volcanoes on the ground are unable to emit large amounts of ash, some of them usually release liquid acids, such as volcanoes in Hawaii. But on the USGS 'list of potentially 1,500 volcanoes, there are some huge volcanoes, such as the supernova in Yellowstone, which can cover the entire United States with ash.
