We finally know where the Yellowstone volcano will erupt next

A detailed look at Yellowstone's magma storage system finds that only one region is likely to host liquid magma in the long term.

New research has pinpointed where theYellowstone supervolcano will likely erupt. It won't blow today, but future eruptions will likely center on the northeastern side of the national park, the new study finds.
Not that Yellowstone is likely to still be a national park by the time it erupts. Any such eruption is expected to take place hundreds of thousands of years from now, study co-author Ninfa Bennington, a volcano seismologist at the Hawaiian Volcano Observatory, told Live Science.
The research, published Jan. 1 in the journal Nature, found that rather than being stored in one big blob under Yellowstone, melted magma lurks in four separate reservoirs within the crust of the caldera.
To the west, these reservoirs do not touch the deep mantle rocks that would otherwise heat them from below, keeping them liquid and eruptable. But to the northeast, near a landmark called Sour Creek Dome, deep rocks are heating the magma trapped in the crust. That means that while magma under the western side of Yellowstone will likely start to cool and solidify, the northeast will stay hot.
