These secret pockets of magma can’t be detected and are potential lava bombs.

Abstract: Because ice shelves respond to climatic forcing over a range of time scales, from years to millennia, an understanding of their long-term history is critically needed for predicting their future evolution. We present the first detailed reconstruction of the Larsen C Ice Shelf (LCIS), eastern Antarctic Peninsula (AP), based on data from sediment cores recovered from below and in front of the ice shelf. Sedimentologic and chronologic information reveals tha...

Credit: Shane Rooyakkers. Boulder, Colo., USA: Volcanologists' ability to estimate eruption risks is largely reliant on knowing where pools of magma are stored, deep in the Earth's crust. But what happens if the magma can't be spotted? Shane Rooyakkers, a postdoctoral scholar at GNS Science in New Zealand, grew up in the shadow of Mount Taranaki on the country's North Island, hiking on the island's many volcanoes. Today, his research is revealing hidden dangers that may have been beneath his feet all along. A new study, published yesterday in Geology, explores a threat volcanologists discove...
