Hawaii’s slow-moving lava flow stalled for now

This photo taken on Oct. 31, 2014, and released by the U.S. Geological Survey, shows a hole left behind by a large tree that was surrounded by lava, burned through at its base and collapsed onto the solidified flow surface, near the town of Pahoa, Hawaii. The end of the tree trunk is glowing, and flames from burning wood are emanating from the hole. Geologists say this represents an under-appreciated hazard of the lava flow field, as trees that were surrounded by lava can fall long after the leading edge has passed by. The tip of the flow that remains halted in a Pahoa farmer's yard is now cool to the touch, but a few hundred yards upstream an active stretch of lava is "inflating," or filling with fresh lava.

This Oct. 30, 2014 photo from the U.S. Geological Survey shows lava near the leading edge of the flow oozing over a concrete slab and towards a tangerine tree before solidifying near the town of Pahoa on the Big Island of Hawaii. Lava from a vent at Kilauea volcano has been sliding northeast toward the ocean since June. The 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. (AP Photo/U.S. Geological Survey)

This Oct. 30, 2014 photo from the U.S. Geological Survey shows where lava flow has come into contact and inflated against an artificial berm, to a level much higher than that of the berm, on private property near the town of Pahoa on the Big Island of Hawaii. Note that the flow has inflated to a level much higher than that of the berm. Lava from a vent at Kilauea volcano has been sliding northeast toward the ocean since June.

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.
