The LERZ continues as usual, although there are tantalizing hints that change could be on the way:
July 8, 2018. USGS: “Fissure 8 (lower right) and open lava channel leading to the northeast. Geologists noted small lava-level fluctuations in the open channel overnight, which indicates intermittent variations in lava discharge from fissure 8. An increase in lava levels was noted about 1.5 hours after the collapse-explosion event at the volcano’s summit at 02:55 a.m. HST. Evidence of a couple of recent, short-lived channel overflows were observed early this morning, but they had not reached the edge of the flow field. The small steam plumes in distance mark locations of fissures that erupted in early May at the beginning of the ongoing eruption.” (Full-sized)
Fissure 8 gushes within its large cone, Fissure 22 continues to spatter weakly. The open lava channel from Fissure 8 now ends about 2km (1.2 mi) from the coast:
July 8, 2018. USGS: ” 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). Clearly, lava moves into and through the molten core of the thick ‘a‘ā flow across a broad area from both the sides and end of the channel.” (Full-sized)
From the end of the channel, the lava dives under the crust of the slightly older flows that buried Kapoho Bay. It emerges again along a very broad ocean entry:
July 18,2018. USGS: “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.” (Full-sized)
According to USGS/HVO, the ocean entry is “primarily along the northern section,” as it has been for the past few weeks. However, to judge by today’s @hotseasthawaii overflight, there’s notable ocean entries to the south as well. Besides the lava that reaches the ocean, USGS reported lava “oozing out” to the north and southwest of the main a’a field just inland, as one can see on Friday’s thermal map. A few Kapoho Beach Lots houses are hanging on, threatened by the northern “ooze-out.” The southwestern “ooze-out” — several local photographers have reported an unconfirmed “southern lobe” lava flow— is within a few hundred yards of Ahalanai Warm Pond and Kua O Ka La Charter School:

Italy’s Cosmo-Skymed satellite sent down another radar image of Kilauea caldera today:
July 8, 2018. USGS: “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. […] The most recent radar scene, from July 8, shows continued motion along cracks over a broader area of the caldera floor, extending east of Halema’uma’u (these cracks are the scarps seen in recent photographs from the Keanakākoʻi overlook area).” (Full-sized)
