This Oct. 22, 2014 photo provided by the United States Geological Survey shows lava flow slowly moving through thick vegetation and creating thick plumes of smoke as it advances on the town of Pahoa on the Big Island of Hawaii. Frequent methane explosions occur, resulting from cooked vegetation releasing methane which then ignites. The explosions can range from small puffs to loud cannon-like blasts, and are an additional hazard in the immediate area of the flow margin. (AP Photo/U.S. Geological Survey)
