Yellowstone hotspot. The Yellowstone hotspot is a volcanic hotspot in the United States responsible for large scale volcanism in Idaho, Montana, Nevada, Oregon, and Wyoming, formed as the North American tectonic plate moved over it. It formed the eastern Snake River Plain through a succession of caldera -forming eruptions.
Yellowstone is centered on a huge, dormant volcano. The hydrothermal explosion did not indicate new activity within the volcanic system, which remains at normal levels, according to the U.S ...
“Monitoring data show no changes in the Yellowstone region. Today’s explosion does not reflect activity within (the) volcanic system, which remains at normal background levels of activity.
The Yellowstone Caldera, sometimes referred to as the Yellowstone Supervolcano, is a volcanic caldera and supervolcano in Yellowstone National Park in the Western United States. The caldera and most of the park are located in the northwest corner of the state of Wyoming. The caldera measures 43 by 28 miles (70 by 45 kilometers), and postcaldera ...

About 33.9 million ago, the Oligocene epoch of the Paleogene period begins. The Mid-Tertiary ignimbrite flare-up begins 40 million years ago and lasts until 25 million years ago. Bennett Lake Volcanic Complex erupts 50 million years ago with a VEI 7 850 cubic kilometers (204 cu mi) of tephra.
Yellowstone, for instance, is hit by an average of around 2,000 earthquakes every year, and that seismic activity is not considered out of the ordinary, he said.
