Aug 27, 2014 · Yellowstone is an obvious target for ash distribution studies, as it provides an opportunity to understand very large eruptions that generate umbrella clouds, which spread radially in the atmosphere (see last image below).
The most likely explosive event to occur at Yellowstone is actually a hydrothermal explosion (a rock hurling geyser eruption) or a lava flow . Hydrothermal explosions are very small; they occur in Yellowstone National Park every few years and form a crater a few meters across.
Jan 21, 2023 · The Yellowstone Caldera — the cauldron-like basin at the summit of the volcano — is so colossal that it is often called a "supervolcano," which, according to the Natural History Museum in London,...
Sep 22, 2014 · A new simulation illustrates the explosiveness of the volcano that lurks beneath Yellowstone National Park in Wyoming. Around 640,000 years ago, the volcano blew its top and coated North...
Sep 5, 2014 · If the supervolcano underneath Yellowstone National Park ever had another massive eruption, it could spew ash for thousands of miles across the United States, damaging buildings, smothering...
May 2, 2016 · Scientists scrutinize past supereruptions, as well as smaller volcanic blasts, to predict what would happen if the Yellowstone Volcano did blow. Here's a deeper look at whether Yellowstone's...
Jun 16, 2021 · The pool of magma underneath Yellowstone is huge, and it will take days or weeks to empty. The explosion will be so powerful that huge amounts of ash will be ejected into the stratosphere.
Aug 27, 2014 · It's just a hypothetical—but if the giant volcano beneath Yellowstone National Park were to erupt, it could blanket the Rockies in ash, send ash as far away as Miami and New York City, alter the climate, and shut down electronic communications and air travel.
Jan 14, 2014 · Scientists have long known that a potential supervolcano eruption is looming in Yellowstone, where some 200 to 600 cubic kilometers of molten rock lies in a magma chamber underneath the National...
Sep 21, 2023 · A massive eruption of the Yellowstone supervolcano would spread deadly ash for thousands of miles, killing plant life and affecting humans in its path. Humans who were in its path would surely die, but it would not mean the extinction of the entire human race.
