Nyiragongo, one of the world's most active and deadly volcanos, could erupt at any time

Located in Democratic Republic of Congo, at the border of Rwanda, the volcano Nyiragongo is considered to be the most active in Africa. Its permanent lake of lava is the biggest of the planet. This volcanic phenomenon, rare and unknown, has been revealed to the public by Haroun Tazieff in 1958 in its movie “Devils’ Rendez-Vous”. Its devastating eruptions threaten the 1 million inhabitants of the city of Goma, which is located at its bottom. The most important was in 1977. The most recent, in 2002, bothered the scientist community because of its violence.
For the Volcanologist Observatory of Goma, it’s a big challenge: increase the knowledge to anticipate the future eruptions and avoid catastrophes. It’s a very complex objective in a very instable region, geologically but also politically. Moreover, to go down inside the crater is very difficult and needs very special competences and experiments.
A team of French and Swiss volunteers, specialists of volcanologic expeditions has taken up the challenge: they go the closest to the boiling lake of lava, in the very heart of the volcano, in order to make samples and analyzes, and to install measuring tools.
This documentary tells the adventure of this exceptional collaboration between passionate volunteers and scientists in a place as dangerous as mythical."

Nyiragongo with its world's largest continuously active lava cannot be described as calm. This fascinating and dangerous volcano is a perpetual threat to the life of the city of Goma, located at the bottom of the mountain where it dominates. Its eruptions have and continue to cause numerous tragedies and disasters. In 1977, more than a thousand people were reportedly killed in the lava flows. In 2002, molten rock destroyed one fifth of Goma, leaving a hundred thousand people homeless.
Jacques Durieux, a volcanologist, was sent to assess the damage and prevent future eruptions. Accompanied by many enthusiasts, Durieux led expeditions to the mythical volcano, but some of them were failures due to the extreme conditions and political instabilities of the country. It was the volcanologist Haroun Tazieff who was the first to descend into the crater of the Nyiragongo volcano, revealing the fabulous spectacle it contained. His work has shown the importance of gas in the eruptive phenomena. Since then, studies have multiplied in an attempt to understand the functioning of energy flows and the convection movements that drive them. The conditions are extreme, the scientists are exposed to heat, magma upwelling, acid rain and the vagaries of the weather. However, they continue their research to unlock the secret of the volcano.
By following the scientists and volunteers closely, Oliver Grunewald tells us about this incredible and rocambolical adventure worthy of a Jules Verne novel. This documentary shows us exceptional images of Nyiragongo and its lava eruptions.
