During the helicopter overflight on June 18, crews captured this image of the growing Halema‘uma‘u crater viewed to the southeast. With HVO and Jagger Museum sitting on the caldera rim (right side, middle where the road bends to the left) it is easier to comprehend the scale of subsidence at the summit.

Map as of 1:00 p.m. HST, June 19, 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.

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.

Fissure 6 (photo center) showed signs of activity overnight, producing small amounts of spatter and feeding short lava flows. Fissure 6 is located about 2.2 km (1.4 mi) downrift from Fissure 8.

In this video taken from the Leilani Estates subdivision, lava at fissure 8 pulses above the cinder cone adding fragments of lava (spatter) that build the cone higher. From fissure 8, lava flows freely over small cascades (rapids) into a well-established channel. Near the vent, lava is traveling about 24 km per hour (15 mi per hour).

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.
