A hydrothermal explosion violently shook part of Yellowstone National Park's Biscuit Basin Tuesday. Here's what we know and the science behind it.
Similar blasts have happened in Biscuit Basin in 2009, 1991 and after the magnitude 7.2 Hebgen Lake earthquake 40 miles (64 kilometers) away in 1959. Yellowstone is centered on a huge, dormant ...
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 ...
An analysis of crystals from Yellowstone's lava showed that prior to the last supereruption, the magma chamber underwent a rapid increase in temperature and change in composition. The analysis indicated that Yellowstone's magma reservoir can reach eruptive capacity and trigger a super-eruption within just decades, not centuries as ...
The 1959 Hebgen Lake earthquake (also known as the 1959 Yellowstone earthquake) [4] occurred in the western United States on August 17 at 11:37 pm in southwestern Montana. [ 4 ] [ 5 ] The earthquake measured 7.2 on the moment magnitude scale , [ 1 ] caused a huge landslide, resulted in over 28 fatalities and left $ 11 million (equivalent to ...
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.

The last time it erupted three times in a year was in 2003, the U.S. Geological Survey's Yellowstone Volcano Observatory said. Unusual eruptions at world's largest active geyser in Yellowstone [Video]
Giantess Geyser is a fountain-type geyser in the Upper Geyser Basin of Yellowstone National Park.It is known for its violent and infrequent eruptions of multiple water bursts that reach from 100 to 200 feet (30 to 61 m).
