Goeff Mackley descended 400 meters into the Marum, an active volcano on Ambrym Island in the Pacific ocean, and stood just a few meters from a massive lava pool. He and Bradley Ambrose, who filmed the video below, were apparently the first people to ever get this close. About the experience, Geoff wrote: "Climbing down to within 30 metres of the lava it was so hot (1150 degrees) that without protection we could stand the heat for 6 seconds before retreating, with heat suit and BA I was able to stand it for 40 minutes."
