The transition zone controls the movement of magma emanating from a volcanic eruption. Can scientists now determine when the next Yellowstone super volcano eruption will occur? Neal Herbert | National Park Service )
Using computer modeling, researchers were able to simulate the conditions beneath Yellowstone, North America's largest super volcano, discovering a zone that controls the movement of magma during a eruption.
Researchers have written new codes for supercomputer models to better understand where magma accumulates in the crust.
The study highlights the magmatic system behind the eruptions. especially where magma breaks out and where it accumulates.
The results, which were published in Geophysical Research Letters showed a transition zone 3 to 6 miles below the surface, where cold and rigid rocks of the upper crust are detached from hot and partially molten rock ,
The transitional zone captures the ascending magmas and causes them to gather in the up to 9 meter high threshold and solidify miles thick. The middle crust separates the magma body. The upper one contains the gas-rich rhyolitic magma, which can burst into explosions.
Researcher Dylan Colón of the University of Oregon said other supervolcanoes around the world might have similar structures.
does not help predict the timing of future eruptions
Nonetheless, the researchers said their work does not help predict the timing of future eruptions, but rather provides an unprecedented look that can help shape the structure of magmatic plumbing systems explain the volcanic eruptions. [1
Prediction of the Next Yellowstone Eruption
19659004] The prediction of a volcanic eruption has progressed significantly in recent decades, and most scientists now believe that there are clues that give an indication of the next Yellowstone eruption decades ago can.
The United States Geological Survey said these precursors to volcanic eruptions include rapid ground deformations and strong earthquake swarms that typically occur days to weeks before the actual outbreak.
"Large eruptions would involve intense precursor activity (well above background levels) at multiple locations in the Yellowstone volcano." The USGS stated
"As with many caldera systems around the world, small earthquakes, and soil uplift Subsidence and gas releases at Yellowstone everyday events and reflect no imminent eruptions. "
