Truth, Fiction and Everything in Between at Yellowstone The Yellowstone caldera is a volcano, and it almost certainly will erupt again someday. It's possible, though unlikely, that future eruptions could reach the magnitude of Yellowstone's three largest explosive eruptions, 2.1 million, 1.3 million and 640,000 years ago. |

Are Volcanoes Picky Eaters? New measurements of the concentrations of elements within magma suggest a volcano's food may be a complex recipe -- and that what kind of magma a volcano prefers may affect its physical features, including the size to which it can grow, according to new research |

Earthly Origin for Desert Formation The Richat Structure in the Maur Adrar Desert is frequently photographed from space. The formation resembles an impact crater, but researchers now say that the famous feature may be the result of magma fluids dissolving sedimentary rocks about 100 million years ago. |
