Small streams of lava enter the ocean across a broad area, shown by the multiple white steam and laze plumes. Lava has added about 380 acres of new land into the sea.

Geologist makes early morning observations of the lava fountain and channelized flow at fissure 8 in Leilani Estates.

View of the southern edge of the growing Halema‘uma‘u crater (middle right) during yesterday's helicopter-assisted work at Kīlauea's summit. The once-popular parking lot (closed since 2008) that provided access to Halema‘uma‘u is no longer—the parking lot fell into the crater this past week as more and more of the Kīlauea Crater floor slides into Halema‘uma‘u.

A temporary GPS station (with radio telemetry for continuous measurement) was installed this week on the Kīlauea caldera floor to track the ongoing subsidence of the summit area. The data will help to characterize the extent and rate of the subsidence.

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.

Geology field crews on the ground near the Kīlauea's fissure 8 midday on June 19, 2018 observed a still-vigorous channelized lava flow being fed by lava fountains at the vent. Standing waves are visible within the channel. Cascades/rapids are visible near the base of the cone, which is an estimated 50 m (164 ft) high.

A thick, dense plume of SO₂ and other volcanic gases billows from the lava fountains at fissure 8 on June 19, 2018. SO₂ emission rates during the 2018 eruption of Kīlauea were so high that they required a new data analysis technique.

This animated GIF shows a sequence of radar amplitude images that were acquired by the Agenzia Spaziale Italiana CosmoSkyMed satellite system. The images illustrate changes to the caldera area of Kīlauea Volcano that occurred between May 5 and June 18 at about 6:00 a.m. HST.

Fissure 8 vigor increased overnight June 18-19 with lava fountains reaching up to 60 m (200 ft). Spatter built up the cone to the east and into the channel. In this photograph, spatter lands on the east cone and flows downward.

Fissure 8 lava fountains obscured by a longer exposure photograph taken early morning on June 18. The incandescent spots along a horizontal line mark the edge of the lava channel. A tongue of incandescent lava leads down to the right - a small overflow from the channel margin.

The northern channel margin of the fissure 8 lava flow. Small hill in the distance is the site of our PGcam. Overflows from the channel can be seen producing shiny black to silver pahoehoe flows (incandescent red breakout visible in center of photo). These flows are building up the channel margins and making the levees more robust.

Fissure 8 cone, lava fountain, and channelized lava flow on the morning overflight - June 19 at about 6:10am HST. The lava channel is very full with many small overflows visible on the channel margins. Overflows are sluggish and move slowly downslope as they build up the levees.

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.

This thermal map shows the fissure system and lava flows as of 6 am on Saturday, June 19. The fountain at Fissure 8 remains active, with the lava flow entering the ocean at Kapoho.The channel is very full and is overflowing to produce short pahoehoe lava flows that overtop the levees.
