The study, published in the journal Earth and Planetary Science Letters, used seismic wave data to assess the texture and composition of the upper magma reservoir, which is about 3 miles (5 km) deep at Yellowstone. The results indicate that the upper chamber consists of 28% melt, which is 8% to 12% more than the 2022 estimate.
Yellowstone’s Upper Magma Reservoir
The study found that the upper chamber consists of 28% melt, which is 8% to 12% more than the 2022 estimate. This higher melt fraction suggests that the magma system is more dynamic and capable of producing larger eruptions than previously thought.
