Yellowstone Caldera - Wikipedia The Yellowstone Caldera, also known as the Yellowstone Plateau Volcanic Field, is a Quaternary caldera complex and volcanic plateau spanning parts of Wyoming, Idaho, and Montana It is driven by the Yellowstone hotspot and is largely within Yellowstone National Park
Yellowstone | U. S. Geological Survey - USGS. gov The Yellowstone Plateau volcanic field developed through three volcanic cycles that span two-million years Two of the eruptions are considered some of the world's largest volcanic events
Yellowstone Supervolcano Revealed - Yellowstone Forever A plume of molten rock that rises beneath the park creates one of the world’s largest active volcanoes, and we can see evidence all around us in the form of geysers, hot springs, mud pots, and other other-worldly thermal features
How big is the magma chamber under Yellowstone? How big is the magma chamber under Yellowstone? Yellowstone is underlain by two magma bodies The shallower one is composed of rhyolite (a high-silica rock type) and stretches from 5 km to about 17 km (3 to 10 mi) beneath the surface and is about 90 km (55 mi) long and about 40 km (25 mi) wide
Mile-wide underwater volcano off U. S. coast expected to erupt soon . . . Axial Seamount sits under the Pacific Ocean about 300 miles from the U S coast Since 1997, scientists have kept a careful eye on it using instruments that measure pressure on the ocean floor Data shows that the volcano has been swelling, with changing rates that hint at an upcoming eruption
Supervolcano at Yellowstone stretches far underground Lurking beneath Old Faithful, scientists have long known there was a supervolcano in Yellowstone National Park with the potential to make the Mt St Helens' eruption look like child's play Now,
Volcano - Yellowstone National Park (U. S. National Park Service) As the underground magma chamber emptied, the ground above it collapsed and created the first of Yellowstone’s three calderas This eruption 2 1 million years ago—among the largest volcanic eruptions known to man—coated 5,790 square miles with ash, as far away as Missouri
Calderas - Worlds Largest - ThoughtCo Calderas are large craters formed by volcanic explosions or by unsupported surface rock collapsing into empty magma chambers beneath the ground They sometimes are referred to as supervolcanoes One way to understand calderas is to think of them as reverse volcanoes
