The Volcano Beneath Yellowstone
Volcanoes at Yellowstone?
Yellowstone National Park is world-famous for its geysers and hot springs. Those thermal features are easy-to-observe evidence of an active magma system beneath the Park. This magma system has produced some of the largest volcanic eruptions in Earth's history - eruptions so large that they have been called "supervolcanoes." One of these eruptions produced a caldera that is about 50 miles across.
Should you be concerned about this? Here are three facts... 1) the most recent super eruption occurred about 640,000 years ago; 2) scientists monitoring the activity at Yellowstone today say "nothing unusual is happening right now"; and, 3) a gigantic eruption is expected to be preceded by significant warnings.
