Yellowstone Super Crater
Yellowstone Park, USA, the lurking ground for super volcano . Many scientists and the public are worried that it will explode at any time and will bring us unexpected catastrophic consequences. In recent years, unusual behaviors of Huangshi have occurred frequently, and the situation is becoming increasingly worse. Therefore, when it will explode has become the focus of daily work by American geological scientists. For us, Yellowstone has become a typical example of supervolcanoes.

On December 18, the Daily Mail reported that in order to further grasp the past and present of the geology of Yellowstone Park and better help scientists accurately predict future super eruptions. Researchers at the University of Illinois, Illinois, used an earthquake tomography technology to explore the underground of western United States deeply and pieced together the background of volcanic activity. Then, the geological history of the Yellowstone area around 20 million years was simulated through supercomputers, and the data results are essentially different from the traditional mantle feather theory volcanic eruption theory. The signs of volcanic activity in Yellowstone Park were found to be more complex and energetic than before.

, Lijun Liu, who leads the new study, said that according to the theory of mantle feather theory, magma will surge out of the surface, mainly due to local abnormalities in the temperature of the crust and mantle boundary. This time, our supersimulation found that mantle plumes in the western United States seem to be sinking continuously, which seems to be a refutation of the mantle plume theory. This shows that the recent anomalies in Yellowstone Park are the result of a Pacific plate originating from the tectonic boundary of the western United States, which is interfering with the rise of plume. The simulated data tell us that the heat source behind the supervolcanic activities in Yellowstone actually originates from the shallow oceanic mantle of the Pacific Ocean.
Volcanic eruption prelude
This study by the University of Illinois challenged previous USGS research, the heat is the result of plume flow below Yellowstone Park. At present, in order to be able to master more convincing data, the research team will further collect and study chemical data from volcanic rocks . If, behind the unusual situation of Yellowstone Park this year is indeed the Pacific plate activity, it will have an adverse impact on the super volcano in Yellowstone Park.
