This October 30, 2014 photo from the U.S. Geological Survey shows a breakout of lava oozing from the margin of the lava flow near the town of Pahoa on the Big Island of Hawaii. These breakouts are located about 100 meters (110 yards) behind the leading edge of the flow. Lava from a vent at Kilauea volcano has been sliding northeast toward the ocean since June. The lava flow has slowed but largely has remained on course. Pahoa residents say the lava will reshape the community yard by yard as it creeps toward the ocean.
