What exactly is a super volcano? Where has a super volcano erupted? Nature has endowed North America with abundant natural resources, but it has also given them a great crisis. If the sword of Damocles hangs overhead, then a super volcano like Yellowstone National Park is more like a time bomb under our feet. Since the second half of the19th century, the United States is rich in natural resources. A large number of European immigrants went to look for opportunities. At the beginning of the 20th century, it replaced the dominant position of British industry and economy, and became the leader of western camp after World War II. All this seems to be a blessing for the country. Later, people gave America the title of God's darling, but its oppression of neighboring countries made people sigh that it was "too far away from the sky and too close to the United States".

Yellowstone National Park is the only active volcano in the world and the most famous super volcano on earth. Among the five lesser-known super volcanoes, the destructive power is not much worse than that of Yellowstone National Park, which can be traced back to the Quaternary, including three in the United States, one in Japan, one in Indonesia and one in New Zealand. In addition to the relatively old extinct volcano, the largest volcano in Lake Doba, Indonesia, according to the geological Quaternary, is not the supervised volcano in Huangshi National Park, but the volcano in Lake Doba in the northern part of Sumatra Island, Indonesia, which is not far from us. If you travel there, you will find a big lake with a crater of 100 km and a width of 30 km.

Quaternary in geology refers to the period when human beings began to develop to the present 2.6 million years ago. Lake Doba appeared in the eastward movement of the Indo-Atlantic plate and was relatively calm after two weeks of eruption. This volcano is still worthy of vigilance. Its geological activities have lasted for nearly a century. The epicenter of the devastating earthquake in the Indian Ocean in 2004 was 300 kilometers away from Lake Doba. Waller Fire and Lake Doba are the biggest volcanic eruptions in the United States. This volcano, located in the state government of New Mexico, erupted twice 16 1 10,000 years ago and1.20,000 years ago, forming a large Bay Crater and a 22km-wide Pa Harito volcanic plateau. Its crater is 22 kilometers in diameter.
