Despite the horrendously huge watermark, here's some pretty incredible footage.

The Most Incredible Volcano Video ever shot ! Geoff Mackley, Bradley Ambrose, Nathan Berg, after an epic struggle with the weather for 35 days, we became the first people ever to get this close to Marum Volcano's famed lava lake on Ambrym Island, Vanuatu. Coming within 30 metres of the lava lake down a watercourse, it was possible to stand the heat for only 6 seconds. With Fire Brigade breathing apparatus and heat proof proximity suit it was possible to stand on the very edge and view the incredible show for over 40 minutes.
As Gizmodo notes, Mackley made a similar trip back in 2010. I've posted both clips.
Watch, AFTER THE JUMP...
