Yellowstone supervolcano may underwater magma ‘anomaly’ researchers suggest

An underwater river or “fountain” of magma is located underneath the Yellowstone supervolcano. Despite the fear that this could lead to a major eruption in the near future, say the experts do not expect it to blow up any time soon.

According to a research paper published in Nature this week, scientists Peter Nelson and Stephen Grand to believe that the magma can stretch as far as Mexico.

The researchers describe “a single, narrow, cylindrical shaped slow anomaly, approximately 350 km in diameter, which we interpret as a whole-mantle plume,” according to the study’s abstract.


The scientists note that the length of the plume was “with the travel times of the core waves recorded by the dense seismic network.”

Or the plume can cause magma to rise in a vertical stream is still unclear, the researchers added. They also noted the Yellowstone hotspot itself, which is the home of the famous bubbling springs, is also a source of discussion.

The researchers also indicate that they have demonstrated that the plume’s existence, because the structure “gradually decreases in strength as it nears the surface and the temperatures in the vicinity of the mantle of at least 650 degrees Celsius (1,202 degrees Fahreneheit), perhaps more than 850 degrees Celsius (1,562 degrees Fahrenheit).

“Our results strongly support a deep origin for the Yellowstone hotspot, and also provide evidence for the existence of a thin thermal mantle plumes that are currently beyond the resolution of global tomography models,” the researchers wrote.


Concerns have surfaced in recent history, especially in the last week when Yellowstone experienced four mini-tremors, that the supervolcano would erupt faster than initially thought.

However, every word of the potential destruction of life as we know it, is incorrect.

According to National Geographic, researchers Hannah Shamloo and Christy To analyzed minerals in petrified as of the most recent eruption in the summer of 2017. What they discovered surprised them – the changes in the temperature and composition only lasted a couple of decades, much faster than the centuries as previously thought.

Despite a number of sensational allegations in the media, the supervolcano is not expected to erupt anytime soon and if it did, the events would not be catastrophic. “There is no reason to think that it will influence mass transport on the way that the eruption in Iceland has no impact on the crops,” told Fox News in October 2017. “There is no evidence to suggest that it might destroy the human race.”

The supervolcano last had a major eruption about 630,000 years ago, To be added. Prior to the last major eruption was 1.3 million years ago, according to a report from ZME Science. A smaller eruption, the most recent on record, occurred 70,000 years ago.
