SUPERVOLCANO in Wyoming, USA, is one of the worst volcanoes in the world
Huge emissions of chemical compounds can rise several kilometers into the atmosphere and damage the ozone ball, scientists warn.
SUPERVOLCANO in Wyoming, USA, is one of the worst volcanoes in the world, the eruption, which could potentially end civilization, experts say. Scientists argue that hydrothermal eruptions when the boiling liquid are connected with the gas under the surface, occur with much greater regularity. A warning from Yellowstone worrying experts. Volcano could harm people powerful hydrothermal explosions, say the observers.
“Hydrothermal explosion large enough to create a crater with a width of 328 feet, it can be expected every few hundred years. The eruption of this scale would have thrown the debris to a distance up to two kilometers into the air and would put at risk those who are nearby”, – experts warn.
United States geological survey (USGS), namely geologist Lisa Morgan wrote about the specifics of what is happening.
“Hydrothermal explosions are violent and dramatic events resulting in the rapid ejection of boiling water, steam, dirt and fragments of rocks. Explosions can reach heights of 2 km [1.2 miles] and leave craters with a diameter of several meters (tens of feet) to more than 2 km of Discarded material, mainly breccia – angular rocks, cemented with clay – you can find the distance from 3 to 4 km from the largest crater,” – said the expert.
Despite the fact that a large hydrothermal explosions are rare events in human time-scale, the potential for future events of its kind in Yellowstone national Park is not insignificant. Lewis Dartnell, Professor of astrobiology at University of Westminster, said recently that the full eruption of Yellowstone could end the humanity. Professor Dartnell told the audience of New Scientist Life in London: “Yellowstone will arrange what we call a SUPERVOLCANO eruption, as it was in the past, and it will mean the end of human civilization”. If Yellowstone becomes active, it kills around 87,000 people in the United States in a matter of minutes. A large plume of ash into the atmosphere will block sunlight and directly affect life, creating a “nuclear winter”.
The massive eruption of the volcano could be the stunning, 6,000 times more powerful than the eruption of mount St Helens in Washington in 1980, which killed 57 people and blew ash into 11 different States and five canadian provinces. If the volcano explodes, there will be climate change as the volcano spews into the atmosphere the huge quantities of sulphur dioxide, which can form a sulphur aerosol that reflects and absorbs sunlight.
