Yellowstone: USGS warns of potential ‘catastrophic’ outbreak
The caldera inside Yellowstone National Park was formed during the last three major events in the last 2.1 million years. It is constantly monitored by the USGS (United States Geological Survey) for any changes to the system that may repeat itself as history may suggest. Poland, the scientific in-charge of the Yellowstone Volcano Observatory (YVO), provides volcanic suicide power during the USGS ‘Overview, Monitoring, Risks and Significant Outcomes’ video.
He said: “The Yellowstone system is made up of multiple magma chambers. We have this mantle-melting discrepancy below the surface.
“But there are many magma chambers that feed this dissolving anomaly.
“There is a very deep hole 15 miles or so below a surface, and it is filled with a very low viscosity magma called basalt.
“It’s the kind of thing that comes out of the air, low viscosity, it flows very easily.

“In turn, it feeds a high-level reservoir of basaltic magma body light – a sticky magma, which is more explosive, and it sits about three miles below the surface in parts of the yellowstone.”
Dr. Poland explains why these rooms are not considered to be filled with molten rock.
He added: “But don’t think of this as a giant magma-bass that is just full of boiling, boiling liquid.
“In fact, most of this is solid. The upper reservoir is only five to 15 percent melted, and the lower reservoir is only two to five percent melted here.
“It’s a ridiculous plastic Y zone that will melt a little in between.

“Yellowstone looks very similar to the magma system, and this is what brings crisis to the region.”
Despite this, the expert then sent a warning about Yellowstone’s capabilities in the event of an accident.
He said: “Everyone knows about the end world explosions.
“These are very big explosions, not the end of the world, but some of them have happened in the last two million years.
“There was one that happened 2.1 million years ago, about 1.3 million years ago, and then 3030,000 years ago, we created the Yellowstone de Ledra in the park itself.

“If that happened today, it would be devastating for the central part of the United States.
“We’ve emulated how ash falls and ash will blanket most of the U.S., this is probably 63 when this caldera formed 6,311,000 years ago.”
However, the expert detailed the type of eruption that is likely to be seen in the near future of geology.
He continued: “But the likelihood of such an event is very remote, it happens once or twice every million years.

“The interval between these things is more than 700,000 years between events.
“All that happens is lava flows. Since the last large Yellowstone eruption, 631,000 years ago, there have been about two dozen lava flows, and you can see them in these different colors.
“The initial pulse of lava flow activity was 500-600,000 years ago.
“We had these orange bits of lava coming out, and then there was another pulse of activity that came about 170,000 years ago to 70,000 years ago, which gave us all this pink color. [shaded] Lava here. “
