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 recove...

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 Earths crust. But what happens if the magma cant be spotted? Shane Rooyakkers, a postdoctoral scholar at GNS Science in New Zealand, grew up in the shadow of Mount Taranaki on the countrys North Island, hiking on the islands many volcanoes. Today, his research is revealing hidden dangers that may have been beneath his feet al...
