The eruption of Yellowstone National Park volcano in the United States means that 212 is coming soon?

Its explosive power is equivalent to 1 million Hiroshima atomic bombs. Volcanic ash will erupt 5 kilometers into the sky, and the amount of eruption will reach 25 million tons. America will be destroyed in an instant, and volcanic ash will spread all over the world within two days. Then, with the arrival of nuclear winter, the thick volcanic ash will block most areas of the earth, and the sun will not shine on the earth. A large number of animals and plants will begin to die, and black acid rain will spread all over the world. This situation will last for 6-1 years.

according to geologists' calculations, the Yellowstone super volcano has erupted hundreds of times in history, starting with 16.5 million years ago and ending with 63, years ago. And its eruption cycle is about 6, years. Coupled with the increasingly intense solar activity in recent years, it seems that the Yellowstone super volcano will erupt soon. It is estimated that its power may be 1, to 8, times that of Mount St. hellens in the United States.

according to the estimation of scientists in the United States and Britain, everything within 1, square kilometers, including Yellowstone National Park, will be swept away by the debris flow of the volcano after the eruption of Huangshi super volcano. Debris flow is a volcanic material with a temperature as high as several hundred degrees, which may destroy everything along the way at a speed of several hundred kilometers per hour or even supersonic speed. About 8,-1, people will die from debris flow. Within 1 kilometers, volcanic ash will be as thick as 2 to 6 centimeters, crushing most roofs. Hundreds of thousands of people may have died or been seriously injured. Volcanic ash will reach most parts of the northern United States in a few days. In many areas, including Denver, Omaha, St. Louis, Chicago, Indianapolis and Detroit, volcanic ash will enter the power grid, resulting in power outages, communication interruptions, pollution of water sources and grain, and traffic paralysis. Fluorine carried in volcanic ash can also cause fluorosis. Volcanic ash will reach Europe in a week. However, the most dangerous gas is sulfur. The sulfur spewed by the volcano will form a sulfur layer around the world within three weeks, causing a large-scale cooling. In three years or longer, the temperature in the United States, Europe and other places may drop by 13 degrees. After the large-scale climate change, the warm and humid air flow in Southeast Asia will disappear, and the precipitation in Southeast Asia and China will be greatly reduced. If it breaks out, it will affect the climate of the whole country and even the extinction of species, and the tragedy of mankind will really come.
