HVO geologist measures 260 degrees C (500 degrees F) along ground cracks near fissure 10 in Leilani Estates. Geologists routinely make temperature measurements to track changes throughout the fissure complex in the lower East Rift Zone.

Lava from fissure 8 travels about 13 km (8 mi) to the ocean in an open channel. Lava remains incandescent (glowing orange) throughout its journey. The ocean entry is at upper right.

Sluggish pāhoehoe briefly spills over a section the levee along the well-established lava channel. Such overflows generally travel short distances measured in meters (yards).

Fissure 8 lava fountains reached as high as about 50 m (164 ft) during the past day.

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.

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.

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.

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.

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.

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.

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.

An HVO geologist uses a thermal camera to measure the temperature (about 93 degrees C or 200 degrees F) of a ground crack near fissure 9.
