Forty minutes of staring into what might resemble the bowels of hell might not be for everybody, but for Geoff Mackley, Bradley Ambrose, and Nathan Berg, a recent trek to the edge of the lava lake at Vanuatu’s Marum Volcano was an experience they’ll never forget. Mackley, who is famous for these types of endeavors, describes the accompanying footage as “The most incredible volcano video ever shot!” and viewers can be the judge.

Wearing special suits to withstand the searing heat, after enduring severe weather during an expedition that lasted nearly two months on the remote island of Ambrym in the South Pacific nation of Vanuatu, the crew climbed alongside the boiling vat of lava (reaching 1150 degrees Fahrenheit) for a brief but spectacular view of the one of nature’s most ferocious spectacles.

“Coming within 30 meters of the lava lake down a watercourse, it was possible to stand the heat for only 6 seconds,” Mackley states in the video description. “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.”

States Mackley, a New Zealand filmmaker, on his website: “Life is either an incredible adventure or it’s nothing at all.”
