Molten rock lives only a couple dozen miles beneath your feet. Occasionally, the pressure builds and it explodes out onto the surface; sometimes with forces greater than our atomic bombs.
As much as lava flows may be destructive, they’re also responsible for building islands, mountains and continents. Lava is one of our more easily-observed natural disasters, as some of the flows move rather slowly. But just because it’s flowing slowly, doesn’t mean it shouldn’t be feared.
People who love to watch lava flows are called “Lava Junkies” and they travel the world to experience the majesty of these burps of molten rock. Follow this junkie as he explores one of his favorite volcanoes. via Discovery Channel
