Yellowstone is supervolcano; has huge magma, molten lava reservoir, finds study
Yellowstone supervolcano is known for having magma beneath its surface. But a recent study concludes that the Yellowstone National Park has massive amount of magma underneath the massive Yellowstone Park.
The latest study makes it amply clear that the Yellowstone is nothing short of a supervolcano and that it houses one of the biggest reservoirs of magma.
The latest study was conducted by scientists associated with University of Utah. Seismologists associated with the UoT have discovered massive amount of sizzling molten rock underneath the Yellowstone Park.
While talking about the study and the finding lead author Hsin-Hua Huang says, â€œFor the first time, we have imaged the continuous volcanic plumbing system under Yellowstoneâ€¦That includes the upper crustal magma chamber we have seen previously plus a lower crustal magma reservoir that has never been imaged before and that connects the upper chamber to the Yellowstone hotspot plume below.â€
Researchers claim that despite massive amount of magma, it is not going to erupt anytime soon.
The findings of the study that have been published in the journal Science this week, says that the Yellowstoneâ€™s plumbing system is no larger â€“ nor closer to erupting â€“ than before. Researchers who had deployed advanced techniques to make a complete image of the system that carries hot and partly molten rock upward from the top of the Yellowstone hot-spot plume were able to conclude that it was safe and it was not going to erupt earlier than the previous estimates.
Another seismologist while Victor Tsai while talking about the study says, â€œKnowing that you have this additional reservoir tells you you could have a much bigger volume erupt over a relatively short time scaleâ€.
Studies claim that no major eruption is going to happen before next 90,000 years. But as the United States Geological Survey (USGS) points out, such calculations are statistically meaningless. â€œNevertheless, we cannot discount the possibility of another such eruption occurring some time in the future, given Yellowstone’s volcanic history and the continued presence of magma beneath the Yellowstone calderaâ€¦Yellowstone’s 2-million-year history of volcanism, the copious amount of heat that still flows from the ground, the frequent earthquakes, and the repeated uplift and subsidence of the caldera floor also testify to the continuity of magmatic processes beneath Yellowstone and point to the possibility of future volcanism and earthquake activityâ€ says USGS.
