In this special sponsored episode, Cath Rule from Rayburn Tours, Dr Rob Parker from Time for Geography and Dr Rhian Meara of Swansea University join John to talk about their recent expedition to the island of Heimaey to complete a joint project around the eruption in 1973 and its impacts.

They talk about the tectonics of the island, the events of January 1973 and their effect not only on the island's residents but on monitoring systems and impact management today.

They look into the process of putting together a project of this size and how Time for Geography works with academics and organisations like Rayburn tours to put together real and engaging resources for schools.
