Huge volcano under Yellowstone Park rising - Technology & science
The huge volcano under Yellowstone National Park has been rising at an unprecedented rate during the past several years, according to a new study.

In the ancient past, the Yellowstone volcano produced some of the biggest-known continental eruptions, but the recent rising doesn't mean another doomsday eruption is looming, scientists say.

The recent rising is unprecedented for Yellowstone's caldera — the cauldron-shaped part of the volcano — but it's not uncommon for other volcanoes around the world. The new study has simply revealed a more active caldera at Yellowstone than scientists realized.
