There are concerns that the dormant giant may erupt after scientists studying the Yellowstone supervolcano found activity deep within the crater.
The Wyoming volcano, which is part of Yellowstone National Park, has the potential to erupt with devastating force at magnitude 8.
And some residents and experts think the volcano is due because it hasn't burst in roughly 640,000 years.
Magma inside the supervolcano's crater, or caldera, is migrating northeast, changing the concentration of volcanic activity as it does, according to research.
In contrast to earlier warnings in the western region, this indicates that if the volcano were to erupt, it would occur here.
The 1,350-square-mile crater in the park's western-central region is known as the Yellowstone Caldera, and it was created hundreds of thousands of years ago by the volcano's catastrophic eruption.
The majority of this magma, the scientists discovered, is kept in separate subterranean reservoirs, preventing it from becoming concentrated enough to trigger an eruption.
Although the shift may cause an eruption in the northeast, scientists stated their results indicate that the supervolcano will not explode during our lifetimes.
Lead author Ninfa Bennington, a research geophysicist at the Hawaiian Volcano Observatory, told the Washington Post, "We have regions that are capable of eruption nowhere in Yellowstone."
"There is a lot of magma there, but it is not sufficiently connected." A comprehensive magnetotelluric study was conducted throughout the Yellowstone Caldera by Bennington and her associates.
