Volcanoes are vents that extend from the crust of the Earth and eject lava, ash, and debris into the air when magma pressure builds. A volcano is considered active as long as there has been an eruption within the last 10,000 years....

When Ross Maguire was a postdoctoral researcher at Michigan State University (MSU), he wanted to study the volume and distribution of molten magma underneath the Yellowstone volcano. Maguire used a technique called seismic tomography, which uses ground vibrations known as seismic waves to create a 3...
The Hawaiian Islands were formed in this manner as well as the Yellowstone Caldera (supposedly). What are the Features of Volcanoes? The classic view of a volcano is of the classic mountain shape that starts to erupt from the top of the land mass and has a large crater towards the summit...
At first known as Rock Yellow River, later it became known as the Yellowstone River. Yellowstone is home to many different species of plants. However, the park is most special because of what lies underneath it. It sits on top of an ancient super volcano. And it re...
What caused Mount St. Helens to form? What is a metamorphic rock formed from basalt? What caused the Krakatoa volcano to erupt? Who discovered the Yellowstone Caldera? What are geological features of volcanic activity? What orogeny formed the Cascades?
oddly, had not troubled anyone before: he couldn’t find the park’s volcano. It had been known for a long time that Yellowstone was volcanic in nature — that’s what accounted for all its hot springs and other steamy features. But Christiansen couldn’t find the Yellowstone volcano anywhe...
Yellowstone, in the U.S., is widely known for its super-eruption abilities, too: Some Yellowstone eruptions over the past few million years created layers of volcanic lava rock over 1,300 feet (400 meters) thick. How a volcano super-eruption will impact Earth...
Yellowstone National Park Thisis the largest geyser field in the world found in America. It has approximately 500 geysers spread out on a field. This might be the one giving inspiration to all the films showcasing dangerous geysers. It is home to more than half of the total geysers on Eart...
In addition to active volcanoes, several places on Earth contain what are called "supervolcanoes." These are geologically active regions that lie atop massive hotspots. The best known is theYellowstone Calderain northwestern Wyoming in the U.S. It has a deep lava lake and has erupted several ...
