Volcano Hunters

Just watching footage of an erupting volcano is thrilling. But camping out below a lava-spewing crater—through storms and zero-visibility fog—takes that thrill to levels bordering on insane. Volcanologists Steve and Donna O'Meara do just this to test a controversial theory: that the gravitational pull of the moon has a significant effect on determining when a volcano erupts. In this video, we witness their pilgrimage to Italy's Stromboli, one of the world's most continuously active volcanoes.
