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 ...
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 ...
A study published in GSA Today, the monthly news and science magazine of the Geological Society of America, identified three fault zones where future eruptions are most likely to be centered. [123] Two of those areas are associated with lava flows aged 174,000–70,000 years ago, and the third is a focus of present-day seismicity. [123]

Visitors ran for safety at Yellowstone National Park after a hydrothermal explosion sent rock and steam spewing into the air north of the Old Faithful geyser Tuesday, park officials said.
What triggered this series of events has not yet been clearly established, but volcanologists believe a large earthquake could have played a role by accelerating the melting of nearby glaciers and thus depressurizing the hydrothermal system. Alternatively, rapid changes in the level of Yellowstone Lake may have been responsible.
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 ...
