Yellowstone National Park Magma Chamber
Volcanic eruptions sometimes empty their stores of magma so swiftly that the overlying land collapses into the emptied magma chamber , forming a geographic depression called a caldera. This is how the magma chambers under the Yellowstone volcano caldera was determined. This can cause a chain reaction. When magma intrudes the crust it cools, crystallizes, and releases gases that had been dissolved in the melt.

The newfound chamber see below sits 12 to 28 miles beneath the supervolcano and is four Yellowstone National Park Magma Chamber bigger than a shallower chamber above it that scientists already knew about. Rare eruptions. Is all of this magma something to worry about? The researchers said in the statement that the discovery doesn’t mean pockets of magma are growing larger — or that the supervolcano is about to erupt. The Glacier National Park To Great Falls Mt of a supervolcano eruption happening in any given year is 1 in , and the last major eruption wasyears ago.
But the discovery gives scientists a better understanding of Yellowstone’s complex subsurface “plumbing” system that carries hot and partly molten rock upward. The upper magma chamber Yellowstone National Park Magma Chamber Yellowstone National Park’s geysers and was responsible for three ancient volcanic eruptions that coated much of North America in ash, the Associated Press reported.
The researchers used instruments called seismometers to measure the seismic waves generated by earthquakes in order to determine the type of rocky material deep beneath Yellowstone. The researchers examined data from quakes in Utah, Idaho, the Teton Range, and Yellowstone itself as well as data from distant temblors.
For example, it will be interesting to see if the existence of the lower crustal magma reservoir is a common feature for all the volcanic systems around the globe. What else is hidden beneath our feet inside Earth? Check out the “Talk Nerdy To Me” video below.
The upper magma chamber powers Yellowstone National Park’s geysers and was responsible for three ancient volcanic eruptions that coated much of North America in ash, the Associated Press reported. Using GPS and satellite imagery records going back decades, the scientists determined that these changes have been happening for several decades. That such gases were found at Yellowstone is indicative of the ground increasing in temperature, perhaps of magma rising in the lower levels which heats the upper magma. As the pressure built up, the land above the magma rose.
