Mt. Yasur volcano, Tanna Island, Vanuatu.
We flew over this active volcano in a small Cessna, then hiked up to the rim at sunset. You stand there peering into the crater, with bursts of flaming rock flying up and over your head. Just when you think you’re brave enough to stay a moment longer, the entire mountain roars to life like an angry bull and you take a step back. As if that step would actually matter.
