Scientists have long monitored Yellowstone’s volcanic activity, but a new study suggests that there’s no cause for concern about impending eruptions. The study indicates that the amount of molten material pooled in one area is not sufficient to trigger violent eruptions like those seen in the past.
Yellowstone’s unique geology is fueled by a hotspot, where magma from the Earth’s mantle rises through the crust. This produces two types of rock: basaltic lava and rhyolite, which can cause explosive eruptions. Historically, rhyolitic eruptions have posed the greatest risk to the area.
However, distinguishing between these two types of molten material is challenging, especially when they’re several kilometers below the surface. Recent studies have struggled to provide clear answers due to limited resolution and focus. The new research provides a more comprehensive understanding of Yellowstone’s geology and reduces concerns about imminent threats from volcanic activity.
