The Astonishing eruption of the Calbuco Volcano in Chile has numerous scientists rethinking the risk of the volcano that they didn’t consider threatening.
For years, it has been recognized that Yellowstone National Park has concealed a supervolcano underneath its soil, potentially one of the largest in the world, yet the park services has permitted visitors to just walk upon the soil and take photographs with Old Faithful and other geysers in the park.
A new finding of a massive blob of magma underneath Yellowstone has many scientists questioning if there is a greater risk than earlier thought.
Live Science noted that the blob of magma is much more enormous than earlier believed to be. Scientists have been conscious of the magma’s existence for quite some time, but have never really been capable to effectively calculate its size until now.
New studies have uncovered that the magma enclosed within the supervolcano is sufficient to fill the Grand Canon at least 11 times. The bulk of the magma is enclosed within the lower crust of the Earth, at a depth of between 12 and 28 miles deep.
The dimensions of the magma blob is about 44 miles wide and 30 miles long, about 11,200 cubic miles.
In spite of the massive dimensions of the magma blob, scientist do not surmise the Yellowstone supervolcano is anymore hazardous that they considered it to be, and think it is still fairly safe for visitors to check out the majestic national park.
They think the pressure is vented more than enough to hold back a significant eruption in the foreseeable future. Researcher Robert B. Smith claims that the discovery may actually help reduce the dangers of the magma blob, as scientists acquire a better understanding of the supervolcano and how it responds with environment.
He also feels the chances of an actual eruption in Yellowstone, which could happen inside the next few thousand years, is roughly 1 in 70,000, similar odds to being hit by lightening.
“The actual hazard is the same, but now we have a much better understanding of the complete crustal magma system,”
In spite of the low possibility of eruption, CNN warns that an eruption at Yellowstone would be catastrophic enough to transform the world as it is known, making the eruption at Mount St. Helens appear like a firecracker.
In 2003, Yellowstone closed down to the public when temperatures increased the climate of the ground to roughly 200 degrees just a few inches under the surface.
Park officials were worried that visitors could possibly burn their feet. During the time of the closing, some geysers dried out from the heat and sap in some of the trees started to boil.
