The caldera clearly visible today is the later Henry's Fork Caldera, which is the source of the Mesa Falls Tuff. It was formed 1.3 Ma in an eruption of more than 280 km 3 (67 cu mi). The two nested calderas share the same rim on their western sides, but the older Island Park Caldera is much larger and more oval and extends well into Yellowstone ...
The caldera — a 50-mile-wide volcanic crater — is the remnant of a pair of massive volcanic eruptions thrown up by the Yellowstone hotspot as it wandered east to its current location. At its ...
Yellowstone is the hotbed for the geologic hazard worldwide and explosions occur as many as a couple times a year, Michael Poland, the scientist-in-charge at the observatory, told USA TODAY. What ...
