During the overnight hours, the UAS (Unoccupied Aircraft Systems) team flew sections of the lower East Rift Zone, monitoring fissure 8 activity and reports of small overflows from the lava channel. This view of fissure 8 and the upper lava channel shows roiling lava fountains remaining within the cinder cone and a flowing incandescent channel. The black jigsaw-like features in the lower center, are pieces of cooled lava crust flowing on the surface of the channel. Photo taken Tuesday, July 3, 2018 courtesy of U.S. Geological Survey
