The U.S. Geological Survey reported that a small lagoon has been created at the Pohoiki boat ramp as of Wednesday, Aug. 15, 2018, due to long-shore transportation of black sand that is accumulating from the jetty to the shoreline.

The Fissure 8 cone still hosts a small pond of lava, but no new lava has entered the existing channel in over a week. Lava may intermittently enter the ocean between the Kapoho Bay and Isaac Hale Beach Park areas until residual lava contained within the existing flow is depleted. Given the dynamic nature of Kīlauea’s eruption, map details shown here are accurate as of the date/time noted. Shaded purple areas indicate lava flows erupted in 1840, 1955, 1960 and 2014-2015.
