Imagine waking up one day and seeing a lava flow inching towards your neighborhood. Inexorably creeping forward, the molten flow slowly consumes everything in its path, trees, concrete, cars, everything, absorbing all it encounters into the flow, spitting out great plumes of sulfuric acid and other poisonous gases.

The big island of Hawaii (the largest of the Hawaiian islands) is home to five separate volcanos, three of which are active, one of which, Kilauea, spits out lava continuously. Flow from a recent Kilauean eruption has made its crawl to a neighborhood once deemed safe.

All of this is happening incredibly slowly. In this particular case, the lava creeps forward at about 10 feet per hour. The destruction of a house shown in the video below took more than 24 hours.

If you are interested in exploring a lava flow on your own, take some time to read this warning page. Hiking out on the flows is one of the most exciting (and possible stupid) things I’ve ever done in my life. Rarely in life do you have the opportunity to witness the raw power of nature from such an intimate vantage point. Not sure who filmed this video, but whoever you are, be safe.
