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).

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.

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.

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.

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.

Lava from fissure 8 is fed into a channel that travels about 13 km (8 mi) to the sea. A plumemarks the location of fissure 8, visible in the upper right; a small plume in the upper center marks the location of fissure 22.

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 30 at about 6:00 a.m. HST.

Fountains from the fissure 8 spatter cone continue to supply lava to an open channel.

Hawaiian Volcano Observatory geologist Matt Patrick acquires video of fissure 8 and the lava channel from Pohoiki Road/Highway 132. The video is used to document fountain behavior and lava flow characteristics, and how they change with time.

At the Kapoho coast, lava enters the ocean along the northern margin of the flow field. 

Lava was entering the ocean over a broad area this morning. This image shows an active entry area along the northern flow front at Kapoho. View to the south.

Lava flows around islands in the lava channel. The direction of flow is from the upper right to lower left. Field crews can make a rough calculation of velocity by timing large blocks as they pass between two landmarks that are a known distance apart.

During the June 29 overflight, USGS scientists observed multiple active spots along the Kapoho ocean entry producing laze plumes.

High-resolution satellite data are useful for mapping cracks and deformation in the summit caldera at Kīlauea Volcano.

Fissure 8 and the proximal lava flow channel on the morning of June 29. Low fountaining within the cone is still producing a vigorous supply of lava to the channel.

Early morning view of Fissure 8. Lava roils and pours out of the spatter cone into the open channel.
