Deep beneath Japan’s Kikai caldera, a massive magma reservoir is refilling 7,300 years after one of the most powerful volcanic eruptions in Earth's recent geological history. Scientists used underwater seismic surveys to reveal a vast store of magma that appears to have accumulated since the ancient catastrophe. The discovery could help explain how supervolcanoes like Yellowstone and Toba rebuild their magma supplies.
