Expedition Volcano

The first programme follows an extraordinary expedition to one of the world's most dangerous, spectacular and lesser-known volcanoes - Nyiragongo. The 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. But now, an international and local team of scientists are mounting a major expedition to study the volcano. They are attempting to discover the warning signs that it is building towards a new eruption, so they can alert the people of Goma before it erupts again.

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.
