Toba, Thera, Vesuvius, Tambora, Krakatoa, history proves, volcanic eruptions can cause havoc. Hot lava flows, the fireball that came out, the ash cloud that burst into space, tsunami also arise when a giant rock from falling into the sea, even capable of removing human civilization.
So, what would happen if 1,500 active volcanoes on Earth erupted simultaneously - including those in the ocean, which is not all revealed the number and whereabouts.
Although every day, between 10 to 20 mountain eruption, however, the scientists say, chances all the mountains on the planet erupted simultaneously is very small, or even impossible.
However, what happens if that happens? Is there going to be saved? Parv Sethi, geologist from Radford University, Virginia, USA said, even if the only mountain in the land which erupted simultaneously, will trigger a domino effect which is worse than nuclear or atomic winter winter - a potential threat that occurred after the explosion of nuclear weapons. "I can not imagine how bad things happened, I probably would not have survived, kept alive when the condition of the Earth like it."
Two of the biggest threats that would trigger a catastrophe on Earth came from volcanic ash and gases. Meanwhile, pyroclastic flows including lava will only deadly to living beings who live near the mountain - which is not proportional to the number of deaths due to climate change. Sethi predict, a thick layer of volcanic ash will undoubtedly envelop the Earth. Abu also will prevent the entry of sunlight in total.
"This planet will experience total darkness. The process of photosynthesis is not going to happen, damaged crops, and the temperature will drop. Abu will survive in Earth's atmosphere for at least 10 years," he said. Although not all of spitting mountain ash eruptions - such as mountains in Hawaii lava flow that moves slowly, but other mountain in the list of the US Geological Survey (USGS), including the Yellowstone super volcano would bury most of the US with ash. extinction Acid rain down will kill all plants.
Hydrochloric acid are corrosive and foul-smelling, Flurida hydrogen, hydrogen sulfide, and sulfur dioxide can lead to acid rain when condensed in the atmosphere.
Ocean acidification will kill coral and sea creatures that have a shell. Marine food chain is interrupted, the fish will be extinct, as well as other creatures. Researchers have documented a similar link between ocean acidification and mass extinctions in the past with mega-eruption, namely flood basalt - basalt rocks that cover a certain area.
For example, uncontrolled outpouring of lava associated with extinction at the end of the Permian period 252 million years ago, the Triassic period 201 million years ago, and the end of the Cretaceous (Cretaceous) 65 million years ago. "Flood basalt and mass extinctions have relevance," said Paul Renne, a geologist from the Berkeley Geochronology Center in California, the experts to find out the age of the rocks.
The explosion also ejects explosive volcanic ash, dust, and gases into the Earth's stratosphere. The particles will reflect sunlight should reach Earth. In a small scale can cool the Earth, though briefly. As happened when the eruption of Mount Pinatubo in the Philippines in 1991 - which became one of the largest volcanic eruption of the 20th century. Consequently cool the rest of the world to 0.4 degrees Celsius for 2 years
