The lava flow nearest Pahoa on the Big Island appears to be inactive, but Hawaiian Volcano Observatory scientists are continuing to examine the flow field to determine whether the tube system remains alive.

Scientists were expected to fly over the lava field Tuesday and take thermal images of the tube system, said Janet Babb of the Hawaii Volcano Observatory.

The results of the aerial imagery could reveal just how likely it is that lava could reoccupy the tube system downslope, she said.

Hawaii County Civil Defense Administrator Darryl Oliveira said an inspection of the lava field Tuesday morning found no activity in the downslope areas, while small breakouts continue to be observed about 8 miles upslope closer to the summit.

He said there is no immediate threat to area communities.
