Some volcanoes take their time—experiencing protracted, years-long periods of unrest before eventually erupting. This makes it difficult to forecast when... more
Victor Camp has spent a lifetime studying volcanic eruptions all over the world, starting in Saudi Arabia, then Iran, and eventually the Pacific Northwest. The geology lecturer finds mantle plumes... more
Hundreds of volcanoes pockmark the surface of Io, the third largest of Jupiter's 78 known moons, and the only body in our solar system other than Earth where widespread volcanism can be observed. The source of... more
