A lava flow is steaming through lush forests as it creeps across Hawaii's Big Island.

The U.S. Geological Survey has distributed a steady stream of images from the lava flow, including pictures of a breakout of lava near a ground crack system near an abandoned geothermal well site. The lava is burning thick vegetation in the area, and filling the air with smoke.

Kilauea volcano has been erupting continuously for more than 31 years, but a flow started down a flank toward the northeast in late June and is threatening the small town of Pahoa. Progress of the lava flow has come in fits and starts. So far, one home has been destroyed before the flow again stalled.

Hawaii County Civil Defense officials says no advancement has been noted since the weekend
