Don't panic.
The volcano beneath Yellowstone National Park has garnered interest — and worry — because it has had some of the most explosive, dramatic eruptions in the geologic record, he says. In the last 2.1 million years alone, Yellowstone has had three catastrophic eruptions, generating continent-wide ashfalls and disrupting the global climate.Yellowstone’s subterranean magma chambers mostly contain hardened, cooled crystals that are mixed in with some amount of molten material.
“We’re not absolutely pushing the limit in terms of what we can do,” Maguire says, “but we’re getting kind of close.”To “see” beneath the surface, scientists use information gleaned from the speeds of different types of seismic waves as they travel through the ground. Seismic waves known as “S waves” are particularly useful when looking for melt because these waves slow down considerably when they encounter any liquid, such as water or molten magma.
But waves don’t really move in a line; they radiate outward. They diffract. When encountering a subsurface feature that could slow them down, they might bend around it rather than barrel through it. Those additional wave movements add a lot of fine detail to the picture — but they also require a lot of computational power.
