Background image: Crews make visual observations of activity at fissure 8 around 5:30 a.m. HST. Fountain heights this morning continue to reach 70 to 80 m (230 to 260 ft) above ground level. The fountaining feeds a lava flow that is moving to the northeast along Highway 132 into the area of Noni Farms road.
