The previously stalled lava flow front has advanced approximately 15 yards since Friday afternoon, Hawaii County Civil Defense officials said after an aerial assessment Saturday morning.

Between Monday and Friday afternoon, the lava had not advanced at all.

The activity appears sluggish and the front is approximately 25 yards wide, officials said.

The leading edge of the flow remains about 0.6 miles upslope of the Highway 130 and Pahoa Village Road intersection and approximately 700 yards from the Pahoa Market Place complex.

Surface breakouts and activity along both margins on the flow continues upslope and does not pose an immediate threat to area communities, Civil Defense said.

A light wind is causing moderate to heavy vog and smoke to settle across the easter areas of Puna through Hilo.
