Fissure 8 and Leilani Estates viewed from the south. Houses in the foreground are located in the southern portion of Leilani Estates.

Lava entering the ocean as seen through steam and rain early this morning.

The lower section of the fissure 8 lava channel appears to be almost completely crusted over, and the lava level in the channel was lower during this morning's overflight.

This photograph taken during this morning's overflight shows heavy, localized rain at fissure 8 in Leilani Estates.

Small, ash-poor plume associated with the summit collapse explosion event at 9:20 a.m. HST. The pinkish gray plume can be seen on left side of image near the ground.

Southern end of the active fissure 8 flow margin north of the Analannui Park, known as the warm ponds. The flow margin is estimated to be about 500 m (0.3 mi) from the park.

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

Braided section of the lava channel located "downstream" between about 3.5 to 6 km (2.2 to 3.7 mi) from fissure 8 (upper right). The width of the two channels in the middle center is about 325 m (1,065 ft). View is toward the southwest.

Fissure 8 (lower right) and open lava channel leading to the northeast.

View of the partially filled Kapoho Crater (center) and the open lava channel where it makes a 90-degree turn around the crater. The open channel no longer directly enters the ocean. Lava flows freely through the channel only to the southern edge of Kapoho Crater (left side of image).

Lava still oozes from the northern edge of the ‘a‘ā flow near the lighthouse at Cape Kumukahi (upper right). Smoke from burning vegetation marks location of lava oozeouts. View is toward the northeast. 

Multiple ocean entries were active this early morning, each contributing to the prominent "laze" plume above the area. Lava moves from the open channel through the molten core of the broad ‘a‘ā flow field to the ocean. Kapoho Crater is at middle right of photo.

Close view of the "end" of the open lava channel where lava moves beneath the crusted ‘a‘ā flow.

USGS oceanographer Shawn Harrison poses in front of the USGS video camera installation atop the coastal bluff of Barter Island in northern Alaska.

For a short study period, two video cameras overlooked the coast from atop the coastal bluff of Barter Island in northern Alaska. The purpose was to observe and quantify coastal processes such as wave run-up, development of rip channels, bluff erosion, and movement of sandbars and ice floes.

For several years, a special ultraviolet camera has been located near Keanakākoʻi Crater at Kīlauea's summit. The camera was capable of detecting SO2 gas coming from Halema‘uma‘u crater. This morning, the camera was removed because there is very little SO2 to measure these days at the summit.
