BBC - Expedition Volcano (2017)

Chris Jackson, Xand Van Tulleken and Aldo Kane take part in an extraordinary expedition to one of the world's most dangerous, spectacular and least known volcanoes.

Chapter 1: Nyiragongo
In the heart of Africa, deep in the Congo, is one of the most spectacular volcanoes on Earth - Nyiragongo. This spectacular volcano contains a massive boiling cauldron of molten rock - the world's largest continually active lava lake. But it is also one of the most dangerous volcanoes on the planet. It has erupted twice in the last 50 years, most recently in 2002, wreaking havoc and destruction on the people who live in the nearby city of Goma. This region is also dangerous for another reason - it has been racked by war and humanitarian crises for most of the last 30 years, so Nyiragongo is one of the least studied active volcanoes on Earth.

Chapter 2: Nyamulagira
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.
