Volcanoes are fed by magma that rises through cracks in the Earth’s crust, but we do not really understand how these cracks form and what they tell us about the risks of volcanic eruptions. Dr Craig Magee, from the University of Leeds in the UK, is trying to see below the earth’s surface to learn more.

This brochure introduces Craig's work, offers an insight into careers in structural geology, contains an interview with Craig and includes an activity sheet that challenges students to summarise Craig's research in a single diagram of the Earth's crust.
