Our Changing World - Seabed mud and past eruptions

On Our Changing World today, Claire Concannon learns about the Beneath the Waves research programme. It's led by GNS Science and aims to understand more about the two island volcanoes in the Bay of Plenty - Whakaari and Tuhua. As well as mapping the anatomy of the volcanoes, the team are also looking back into their eruptive past to learn about the risks they might pose in the future.
