A novel looking at an eruption in the Yellowstone Caldera written by a practicing Wyoming geologist. Contains a wealth of technical details on the geology of western Wyoming. Vazquez, J. A.; Reid, M. R. (2002). "Time scales of magma storage and differentiation of voluminous rhyolites at Yellowstone caldera". Contributions to Mineralogy and ...
This eruption is considered the climactic event of Yellowstone's third volcanic cycle. The Lava Creek Tuff covers an area of more than 7,500 km 2 (2,900 sq mi) centered around the caldera and has an estimated magma volume of 1,000 km 3 (240 cu mi).
Known as a super eruption for its magnitude, the event emptied out enough volcanic material to produce the 30-by-40-mile-wide caldera. The National Park Service said the eruption covered an area ...
(See Yellowstone Caldera map.) The Henry's Fork Caldera in Idaho was formed in an eruption of more than 280 km 3 (67 cu mi) 1.3 million years ago, and is the source of the Mesa Falls Tuff. [11] The Henry's Fork Caldera is nested inside of the Island Park Caldera and the calderas share a rim on the western side.
The caldera is the enormous volcanic crater left from the last time Yellowstone experienced a giant eruption, 640,000 years ago. It covers an area about 30 by 45 miles .
Yellowstone National Park, known for erupting geysers like Old Faithful, is home to one of earth’s largest volcanic systems, with the capacity to wreak havoc on an entire continent — and ...
This eruption of 2,450 km 3 (590 cu mi) of material is thought to be one of the largest known eruptions in the Yellowstone hotspot's history. This eruption, 2.1 million years ago, is the third most recent large caldera-forming eruption from the Yellowstone hotspot. It was followed by the Mesa Falls Tuff and the Lava Creek Tuff eruptions.

A surprise eruption of steam in a Yellowstone National Park geyser basin that sent people scrambling for safety as basketball-sized rocks flew overhead has highlighted a little-known hazard that ...
