The year 2017 was full of information covering Yellowstone and the potential for an eruption. While we thought we had seen the last of it things are taking a bad turn.
There seems to be something terrifying under the surface of this volcano and that happens to be a 217-mile wide hotspot that reaches temperatures of over 1000 degrees Fahrenheit. This massive volcanic chamber could be alarming. We all know Yellowstone is overdue for an eruption but when is a question no one can truly answer.
Whether or not Yellowstone is going to erupt anytime soon is something many debate over and lots want to push under the radar. Whether it is soon or not, it will erupt eventually, that much is something no one can deny. A study published earlier this month really has me nervous about the whole thing.
The Yellowstone hotspot, located in North America, is an intraplate source of magmatism the cause of which is hotly debated. Some argue that a deep mantle plume sourced at the base of the mantle supplies the heat beneath Yellowstone, whereas others claim shallower subduction or lithospheric-related processes can explain the anomalous magmatism. Here we present a shear wave tomography model for the deep mantle beneath the western United States that was made using the travel times of core waves recorded by the dense USArray seismic network. The model reveals a single narrow, cylindrically shaped slow anomaly, approximately 350 km in diameter that we interpret as a whole-mantle plume. The anomaly is tilted to the northeast and extends from the core–mantle boundary to the surficial position of the Yellowstone hotspot. The structure gradually decreases in strength from the deepest mantle towards the surface and if it is purely a thermal anomaly this implies an initial excess temperature of 650 to 850 °C. Our results strongly support a deep origin for the Yellowstone hotspot, and also provide evidence for the existence of thin thermal mantle plumes that are currently beyond the resolution of global tomography models.
Below you will see some of the figures they went over in their paper. These are in regards to the Yellowstone hotspot itself. A bit terrifying isn’t it? Don’t be too afraid, hopefully, a game plan will be figured out before anything terrible happens.
Express.Co.Uk reported as follows in regards to the study findings above:
And to make the situation even more terrifying, there has been 11 earthquakes in the region since the geysers blew – more evidence of the subsurface action in the magma pits.
Below the surface of the park lies the fearsome Yellowstone Caldera, a super volcano which last erupted approximately 630,000 years ago.
While more research needs to be done this opens a door like no other. As time goes on this issue grows more and more apparent.
I am nervous to say the least. If Yellowstone were to erupt it would kill far more than most people realize. This is something we all need to be aware of.
