In october 2010, the volcanologist Geoff Mackley came up with the crazy idea of descending into the Marum volcano which was active at that time. He gathered a team and went to Ambryum Island, Vanuatu, in an extreme adventure to approach as much as they could of the boiling caldera. To document the furious lava lake up close, they had to descend into the giant pit, facing hazardous toxic gas vapors and foul weather. See how they managed to confront the danger in the video below.
What do you think- challenging or plain crazy?
