Volcanologist (yes, they exist) Geoff Mackley was interviewed by Matt Lauer about this latest jaunt into a volcano.
Mackley, a regular dare devil, descended into the volcano on the Vanuatan island of Ambrym, which he claims has some of the worst weather on the planet. Mackley told Lauer, "The volcano pumps out so much green house gas, it creates its own weather."
While he recognizes that "a lot of people might think I'm crazy," Mackley is thinking about making his volcano rappelling adventures into an extreme tourist trip.
