Aerial view of ground cracks on Pohoiki Road during an overflight of the eruptive fissure area at about 7 a.m. HST. Cracks continued to open and widen, some with horizontal and vertical offsets, in the area during the past 24 hours. These cracks are caused by the underlying intrusion of magma into the lower East Rift Zone. Photo taken Thursday, May 17, 2018 courtesy of U.S. Geological Survey
