This is Planet Hope, a new podcast from The Times in partnership with Rolex and its Perpetual Planet Initiative, hosted by Stories of Our Times as a bonus weekly series each Saturday.In 2022 Mauna Loa, the world's largest active volcano, erupted on Hawaii's Big Island. Fortunately this event didn't result in any fatalities - but the same can't be said for other recent eruptions in places like Indonesia, Tonga and the Philippines. Environment Editor for The Times, Adam Vaughan is joined by volcanologist and Rolex Awards for Enterprise Laureate Andrew McGonigle to learn more about the handheld technology he has developed to predict early warning signs of volcanic eruptions, enabling people living in some of the poorest countries to survive deadly disasters.
