Having crusted over about 0.8 km (0.5 mi) upchannel from the ocean entry, lava oozes from the flow's molten interior to enter the sea along a broad flow front on the northern (Kapoho) side of the flow.

The lava channel from fissure 8 jumped its banks near Kapoho Crater where the channel makes a 90 degree bend. The flow within the channel was diverted around a constricted area and joined the channel again "downstream" to the south (left).

Near the coast, the northern margin of the flow field is still oozing pasty lava at several points in the area of Kapoho Agricultural and Beach Lots.

Lava within the fissure 8 cone roils and churns where it eupts from the vent and flows rapidly down the well-established channel. This image was captured via a Mavic Pro drone courtesy of the DOI/USGS Unmanned Aircraft Systems team.

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 July 4 at about 6:00 a.m. HST.

Black streak on caldera wall (center) is about 50 m (yards) long, and white steam plume (lower right) rises from northwestern part of Halema‘uma‘u. Photo from Volcano House Hotel on July 4, 2018. The configuration of this area changed considerably after the photo was taken, as collapse continued into early August.

During the overnight hours, the UAS (Unoccupied Aircraft Systems) team flew sections of the lower East Rift Zone, monitoring fissure 8 activity and reports of small overflows from the lava channel.

Fissure 8 and the upper lava channel, viewed from the early morning helicopter overflight of the lower East Rift Zone. Recent heavy rains have soaked into the still-warm tephra and the moisture rises as steam (right side of lava channel).

Evolution of a blocked channel, image 2: While observing this area of the fissure 8 lava channel near Kapoho cone during the morning overflight, geologists witnesed an "apartment-building-sized" blockage within the channel give way and be pushed down stream by the pressurized lava behind.

Evolution of a blocked channel, photo 1. A blockage of rafted material within the lava channel causes lava to flow over its banks near the Kapoho cone. In this section of the lava channel a cold lava flow from the 1960 eruption forms a barrier on the north side, which initially directed the channel to the southeast.

Inward slumping of Halema‘uma‘u continues in response to ongoing subsidence at Kīlauea Volcano's summit. This image, taken from a temporary observation post located at Volcano House, shows steep walls on the western side of the crater and sloping piles of rubble from rockfall events.

Fisheye lens photograph of a USGS geologist making observations of the fissure 8 lava channel at sunset July 3, 2018. The field crew is at a high point overlooking the channel near where it makes a 90 degree turn around Kapoho Crater and flows south.

At the coast, the northern margin of the flow field is still oozing pasty lava at several points in the area of Kapoho Beach Lots.

USGS Mavic Pro drone image of the fissure 8 lava channel looking toward the vent. Overflows can be seen as incandescent spots beyond the channel margins. Drone flights and resultant imagery help scientists better identify areas of channel overflows and active flow advancement.

The ocean entry being fed by a crusted over channel has fewer tiny ooze-out channels than yesterday spilling into the water. One larger ooze-out channel making dominant entry plume at the northern end of the broad ocean entry.

Annotated drone image of Kīlauea Volcano's lower East Rift Zone fissure 8 lava channel. Image captured near Kapoho Crater looking east toward the ocean entry. Incandescent flow margin is more easily identified in the dark - specifically here in the area of Kapoho Beach Lots.

Fountains from Fissure 8 spatter cone continue to supply lava to the open channel with intermittent small, short-lived overflows. Overflows appear as lighter gray to silver areas on the margins of the channel.
