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.

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).

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.

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.

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.

The WorldView-3 satellite acquired this view of Kīlauea's summit on July 3. Despite a few clouds, the area of heaviest fractures in the caldera is clear. Views into the expanding Halema‘uma‘u crater reveal a pit floored by rubble. HVO, on the northwest caldera rim, is labeled.

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.

Rocks generate brown dust as they tumble down the western caldera wall during the collapse explosion event on July 5, 2018.

Lava, from small overflows, cools and congeals along the banks of the lava channel to build lava levees. The levees also build up as moving lava pushes cooled crust over the edge.

Near the Kapoho Crater, in the area called Four Corners, the lava channel makes a 90-degree bend. After lava exits the bend, it makes a short drop to form a lavafall. A side channel makes a short surface diversion before rejoining the existing channel.

At 1:20 PM HST on July 5, a collapse explosion event occurred at Kīlauea's summit. The energy released by the event was equivalent to a M5.2 earthquake.

Lava enters the sea along the Kapoho coastline, building a delta that is now over 555 acres in size.

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.

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.
