Preparing to immigrate to the United States, China can't sleep.

Its explosive power is equivalent to 6,543,800 Hiroshima atomic bombs. Volcanic ash will erupt to an altitude of 50 kilometers, 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 in two days. Then with the coming of nuclear winter, thick volcanic ash will cover most parts 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 6-6544 years.

According to geologists' calculations, Huangshi super volcano erupted hundreds of times in history, the earliest was 654.38+06.5 million years ago, and the last was 630,000 years ago. Its eruption cycle is about 600 thousand 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 1000 to 8000 times that of Mount St. hellens in the United States.

According to the estimation of American and British scientists, after the eruption of Yellowstone super volcano, everything within 10,000 square kilometers, including Yellowstone National Park, will be swept away by the debris flow of the volcano. Debris flow is a kind of 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 8000-65438+ ten thousand people died in mudslides. Within the range of 1000 km, volcanic ash will be 20 to 60 cm thick, crushing most of the roofs. 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 failure, communication interruption, water and grain pollution, and traffic paralysis. Fluorine carried in volcanic ash can also cause fluorosis. Volcanic ash will reach Europe within a week. However, the most dangerous gas is sulfur. The sulfur emitted by the volcano will form a sulfur layer around the world within three weeks, causing large-scale cooling. In three years or more, the temperature in the United States, Europe and other places may drop by 13 degrees. After 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 human tragedy will really come.
