Scientists from the University of Utah have recently presented new research at a Fall meeting of the American Geophysical Union in San Francisco that suggests that the size of the magma body beneath Yellowstone is significantly larger than had been thought. However, their report also says the risk of eruption is not very high at this time. Over the past decade, they said improvements to the Yellowstone monitoring network has increased the number and quality of the instruments deployed. The University researchers, in collaboration with a scientist from the Swiss Seismological Service in Zurich, used a method called seismic tomography to create an improved image of the magmatic system beneath Yellowstone. They say that their new research shows that while the magma reservoir is bigger than we thought, the proportion of melt to solid rock (estimated at <10-15%) is similar to previous reports and appears to remain way too low for a giant eruption. Scientist agree that while smaller eruptions are possible in the future, the probability of any sort of eruption at Yellowstone still remains very low over the next 10 to 100 years.
