OK, I normally don’t post these kinds of things, but this is pretty damn amazing so I am compelled to share.
After overcoming 35 days of bad weather Geoff Mackley, Bradley Ambrose, and Nathan Berg, became the first to get this close to the lava lake at Marum volcano on Ambrym Island. They were able to descend to about 30 meters (approximately 100feet) from the lava lake using a respirator Fire and heat resistant suit. Even with this gear, the maximum time that any one of them could stand that close was around 6 seconds. The film was shot from the edge of the volcano rim where they were able remain for about 40 minutes.
Geoff you have more guts than I do, and you shot some really amazing footage. If you are interested in this guys work and he made this, it is available here. Oh and he licenses this stuff for commercial use if you need solid stock footage of things like Volcanos.
