Yellowstone hasn’t had a significant eruption for about 70,000 years, when lava flows formed the Pitchstone Plateau in the southwestern portion of the park, according to the U.S. Geological Survey.

Scientists have studied Yellowstone National Park's magmatic system for years, but a new view of the magma chamber shows the long-dormant supervolcano is not at immediate risk of eruption.

Inside the Yellowstone supervolcano eruption that would 'instantly' kill 90,000 people Geologists recently discovered signs of rhyolitic volcanism in the northeast-shifting Yellowstone caldera.

Cutting-Edge Techniques: Using magnetotellurics, scientists mapped Yellowstone’s magma with Earth’s magnetic field, revealing more magma here than during its last three super-eruptions combined.

A small eruption (at West Thumb) is believed to have occurred as recently as 150,000 years ago. And an explosion some 13,000 years ago left a crater at Mary Bay on the edge of Yellowstone Lake.

Despite widespread fears of a catastrophicDespite widespread fears of a catastrophic "supervolcano" eruption, scientists at the Yellowstone Volcano Observatory (YVO) have suggested that any eruptive ...

The last super-eruption at Yellowstone occurred about 640,000 years ago, and the likelihood of another similar eruption in the near future is extremely low.

It’s known as a super-eruption because it released an estimated 250 cubic miles of material – 1,000 times larger than the Mount St. Helens eruption in Washington state in 1980.
