Ruapehu, the largest active volcano in Aotearoa, and its neighbour Tongariro, are iconic mountains in the central North Island.

GNS volcanologist Graham Leonard joins us to explain the ongoing clash between fire and ice that forges their unique shape, and to share the latest science on these “tenacious rogues”.
