Source of Galapagos Eruptions Not Where Models Place It

Birds flock not far from a volcano on Isabella Island, where two still active volcanoes are located. The location of the mantle plume, to the southeast of where computer modeling had put it, may explain the continued activity of volcanoes on the v...

How Earth's devastating super-volcanoes might erupt

Thank goodness Mount Sinabung isn’t a supervolcano. Credit: Binsar Bakkara/AP Devastating supervolcanoes can erupt simply due to changes that happen in their giant magma chambers as they slowly cool, according to a new study. This finding m...
