The research results are published in the journal Geochemistry, Geophysics, Geosystems. In accordance with the obtained computer model, a powerful volcanic eruption will bring down to 1000 cubic meters of water on the territory of the United States. km of ash. Nearby cities will be covered with a meter layer, and settlements, starting from the Midwest and further, will be covered with a layer of several centimeters.
The giant cloud will be in the shape of an umbrella, evenly covering the entire United States. The computer model created by the Geological Survey is a pilot version of the modeling system being developed, which in the future will make it possible to predict volcanic eruptions and the spread of ash, namely, to determine the thickness of the layer and the direction of cloud movement.
Studies show that Yellowstone eruptions occurred with a frequency of about once every 640-650 thousand years, and that is how much has passed since the last eruption. It is worth noting that we are talking about the world's largest dormant volcano, approximately 55 x 72 km in size, which has recently been showing increased activity.
