USGS Unmanned Aircraft Systems image of fissure 8 looking east. Below the prominent fissure 8 cone, smaller vents above the original fissure emit volcanic gas. Lava has a brighter glow near the vent exit where it is more turbulent than in the downstream channel, which has portions of darker, cooled crust on its surface.
