In the heart of Africa, deep in the Congo, are some of the most spectacular volcanoes on Earth. They threaten the lives of more than a million people, in a region already left shattered by decades of violence.

Now, a team of international and local scientists are here to investigate these rarely visited volcanoes to try and predict when they will next erupt, and to examine how the volcanic forces at work here affect every aspect of life.

For the past week, the expedition has focused on Nyiragongo. Now Chris Jackson and his fellow geologists are heading to the nearby volcano Nyamulagira - one of the most active yet least explored volcanoes on the planet. Few have visited this volcano, for a good reason - the forests that blanket its slopes hide a number of armed groups. The team travel on a UN helicopter flight at treetop level to avoid being hit by groundfire, before landing as close to the active crater as they can. They then have only a few hours to gain as much data as possible to help predict future eruptions.

Beyond Nyamulagira lies a spectacular but dangerous volcanic landscape. The expedition will also explore the hidden dangers and natural wonders contained there - from deadly gases lurking under the vast Lake Kivu, to giant craters left over from sudden explosive eruptions.

Meanwhile, Dr Xand van Tulleken travels across the region to discover how the volcanoes influence every aspect of life here. He sees the legacy of violence created by the volcanic mineral riches. He also explores other natural resources that have the potential to break this cycle of violence, best represented by the mountain gorillas that live on the flanks of the volcanoes. And he meets the people most affected by the ongoing battle to wrest control of these natural resources away from criminal gangs and militias - the widows of park rangers killed in the struggle. Their commitment to protect their natural environment represents the best hope for the future of this troubled region.

Meanwhile, the work the scientists have done will enable local people to better manage the risks of living in such a dangerous part of the world.
