The Fissure 17 flow front has slowed substantially with only small amounts of pasty "toothpaste" lava oozing out from the flow front. However lava continues to be erupted from the active fissure. This lava appears to be accumulating within the flow and has widened the flow margins slightly. Photo taken Thursday, May 17, 2018 courtesy of U.S. Geological Survey
