USGS Mavic Pro drone image of the fissure 8 lava channel looking toward the vent. Overflows can be seen as incandescent spots beyond the channel margins. Drone flights and resultant imagery help scientists better identify areas of channel overflows and active flow advancement. Incandescence (glowing) lava is easier to identify in the dark versus during daylight hours. Photo taken Monday, July 2, 2018 courtesy of U.S. Geological Survey
