45 - 11: Volatile Earth: Volcano on the Brink

Join a team of volcanologists as they explore one of the world's most active and mysterious volcanoes in central Africa: the sleeping giant Nyamuragira. Decades of civil strife have prevented scientists from investigating the volcano, but a brief pause allows an international team of experts to fly by helicopter to the summit to investigate. Discover the region's other hidden, life-threatening volcanic dangers and probe whether magma pressure is building up to threaten another one of its frequent eruptions.
