A new crack 1 km (0.6 mile) long was found on the west (uprift) side of Pu‘u ‘Ō‘ō during HVO’s overflight today. The cracking appeared to be nearly continuous en echelon structures that were heavily steaming. A small amount of lava was apparently erupted from the crack, based on the presence of nearby tiny pads of lava and spatter, but it was no longer active when HVO geologists saw it during the overflight. This photo looks east, with Pu‘u ‘Ō‘ō obscured by low clouds in the upper left corner. Photo taken Tuesday, May 1, 2018 courtesy of U.S. Geological Survey
