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.

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.

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.

Morning overflight of Kīlauea Volcano's lower East Rift Zone by the Civil Air Patrol provides context for the location of the fissure 8 fountain and lava channel within the lower Puna District.

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.

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.

The fissure 8 lava fountain pulses to heights of 50 m (165 ft) within a cinder spatter cone. Fissure 8 feeds lava into the well-established channel that flows to the ocean.

Fissure 8 continues to erupt, feeding lava to a perched channel that extends to the coast. The white laze plume at the distant ocean entry is visible just to the left of the gases rising from the fissure 8 cone (lower right).

This thermal map shows the fissure system and lava flows as of 6 am on Saturday, June 16. The fountain at Fissure 8 remains active, with the lava flow entering the ocean at Kapoho. Very small, weak lava flows have been active recently near the Fissure 16/18 area. The black and white area is the extent of the thermal map.

LERZ Fissure 8 on June 5, 2018 - The sun is behind the observer taking this photo, making the plume appear bluish due to sunlight scattering by tiny sulfate aerosols. The gas plume is against a very dark cloud background, so that no backlighting is affecting the plume view. Photo credit: Allan Lerner, USGS Volunteer

A volcanic gas cloud over the LERZ on May 19, 2018 - In this picture, the sun is illuminating the volcanic gas plume from behind. The plume appears orange in color, as the blue component of the sunlight has been preferentially removed by scattering on tiny sulfate aerosols.

Lava from fissure 8 travels about 13 km (8 mi) down a well established channel (visible in the center of the image) to an ocean entry at Kapoho. Lava is building a seaward delta that is approximately 320 acres in size. The view is to the southwest with the Kapoho area in the lower right.
