One of Earth’s most powerful supervolcanoes is refilling with fresh magma
Scientists have discovered that Japan's Kikai caldera is refilling with fresh magma, providing new insights into how supervolcanoes recover after massive eruptions. This research aims to help experts better predict future volcanic activity at similar sites globally.
Why it matters
Understanding the recharge cycles of supervolcanoes is essential for long-term disaster preparedness and geological risk assessment.
One of Earth's most powerful supervolcanoes is slowly refilling its enormous underground magma reservoir, thousands of years after producing one of the largest volcanic eruptions in recent geological history. Scientists at Kobe University have discovered evidence that fresh magma is accumulating beneath Japan's Kikai caldera, which unleashed a catastrophic eruption about 7,300 years ago.
The discovery offers a rare look at how giant volcanic systems rebuild their magma supplies after massive eruptions. It could also provide important clues about the behavior of other supervolcanoes, including Yellowstone in the United States and Toba in Indonesia, potentially helping scientists improve their ability to recognize warning signs of future eruptions.
