Unveiling Yellowstone's Magma Storage with Seismic Sensors

Scientists have gained new insights into the structure and composition of Yellowstone's magma reservoir using seismic data from hundreds of sensors. The data revealed that the magma is stored in two reservoirs, with the upper reservoir containing more melt than the lower one. The recent study also found that the magma is stored in a sheet-like manner, with horizontally elongated areas of localized magma storage called sills. The improved understanding of Yellowstone's system could help in studying other volcanic systems and improving eruption forecasts. However, many questions about the magmatic system still remain.
