Kīlauea LERZ lava flows and fissures, June 18, 9:00 a.m.

Map as of 9:00 a.m. HST, June 18, 2018. Given the dynamic nature of Kīlauea's lower East Rift Zone eruption, with changing vent locations, fissures starting and stopping, and varying rates of lava effusion, 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.

Kīlauea Volcano — Halema‘uma‘u Crater Slumping

An overflight of Kīlauea's summit on June 18 showed the continued dramatic slumping and collapse of the Halema‘uma‘u crater area. This photo shows the area north-northwest of Halema‘uma‘u near a GPS station, North Pit. This station has subsided about 60 m (197 ft) in the past week.

Kīlauea Volcano — Vacationland Laze Plume

Lava enters the ocean entry in the vicinity of Vacationland, producing a vigorous laze plume. Lava flowing into the ocean has built a delta of flows, rock rubble and black sand, which is over 320 acres in size.

Kīlauea Volcano — Halema`uma`u Crater

Inward slumping of the rim and walls of Halema‘uma‘u continues in response to ongoing subsidence at the summit. Sulfur dioxide emissions from the volcano's summit have dropped to levels that are about half those measured prior to the onset of the current episode of eruptive activity. This gas and very minor amounts of

Kīlauea Volcano — Lava Channels

Occasionally, minor amounts of lava briefly spill over the lava channel levees. The spill overs are the shiny gray lobes along the channel margins. The lava flow field has been relatively stable with little change to its size and shape over the past few days. View to the east, with the
