The Henry's Fork Caldera (1.2 million years ago) produced the smaller Mesa Falls Tuff, but is the only caldera from the Snake River Plain–Yellowstone hotspot that is plainly visible today. [15] Non-explosive eruptions of lava and less-violent explosive eruptions have occurred in and near the Yellowstone caldera since the last supereruption.
Most hotspot volcanoes are basaltic (e.g., Hawaii, Tahiti). As a result, they are less explosive than subduction zone volcanoes, in which water is trapped under the overriding plate. Where hotspots occur in continental regions, basaltic magma rises through the continental crust, which melts to form rhyolites. These rhyolites can form violent ...

Yellowstone is one of the planet's largest volcanic systems, a place where a plume of the Earth's molten core rises up through the solid rock of crust, heating and melting it to form reservoirs of ...
Locations of the Yellowstone hotspot during the past 15 million years. The Bruneau-Jarbidge center is denoted with "12-10" and the light blue area. The Bruneau-Jarbidge volcanic field, also known as the Bruneau-Jarbidge eruptive center [1] is located in present-day southwest Idaho.
Yellowstone encompasses the caldera of a huge, slumbering volcano that shows no sign of erupting any time soon but provides the heat for the national park's famous geysers, hot springs, mud pots ...
Natural vegetation on the Snake River Plain near Twin Falls.
