A sand bar has built up at the end of the Pohoiki boat ramp, but the ramp itself remains intact and there has been no significant lava advance toward the ramp in recent days.

Today's morning overflight saw no new activity at any of the fissures in the lower East Rift Zone. Fissure 8 had only a sluggish lava puddle remaining in the cone, and other fissures, though steaming, showed no signs of reactivation.

Fissure 8 may have slowed down, but HVO scientists are still on the ground in Leilani Estates, monitoring old ground cracks and marking ones that haven't been surveyed before. Monitoring these cracks over multiple days could detect any new signs of magma movement beneath the ground, one of the indicators that fissures might reactivate.

This thermal map shows the fissure system and lava flows as of 6 am on Saturday, August 11. Residual lava in the Fissure 8 flow continues to drain, feeding numerous small ocean entries (shown in main map). In the Fissure 8 cone there were two small lava ponds (shown in small inset map). The black and white area is the extent of the thermal map.

The UAS team (Unmanned Aircraft Systems) flew a mission over fissure 8 to assess conditions within the cinder cone. As shown, fissure 8 contains two small ponds deep within its crater. One pond slowly circulates with an incandescent surface while the other pond is stagnant with a crusted top.

As the Halema‘uma‘u Crater has collapsed, geologists have been able to see older volcanic deposits and features buried beneath decades of lava flows. For instance, two lava tubes were spotted in the southwestern wall of the collapse crater.

Map as of 2:00 p.m. HST, August 9, 2018. Given the dynamic nature of Kīlauea's lower East Rift Zone eruption, with changing vent locations, fissures starting and stopping, and varying rates of lava effusion, map details shown here are accurate as of the date/time noted. Shaded purple areas indicate lava flows erupted in 1840, 1955, 1960, and 2014-2015.

Clear weather this afternoon afforded a stunning view of Kīlauea's summit, which has been "quiet" since August 4, with no significant subsidence or collapses. The flat ledge shown here (center) is part of the former Halema‘uma‘u crater floor, which dropped precipitously between mid-May and early August.

There were small active ooze outs near the coast on the Kapoho Bay and Ahalanui lobes but the laze plume was greatly diminished. Active lava is close to the Pohoiki boat ramp but has not advanced significantly toward it.

A diffuse laze plume this morning afforded a clear view of Isaac Hale Beach Park and the ocean entry, which was being fed across a broad front by viscous pāhoehoe. Lava flows in this area have thus far spared the Pohoiki boat ramp, visible at left.

This thermal map shows the fissure system and lava flows as of 12:30 pm on Friday, August 3. The fountain at Fissure 8 remains active, with the lava flow entering the ocean. The dominant ocean entry points were on the section of coastline near Ahalanui. The black and white area is the extent of the thermal map.

Hawaiian Volcano Observatory field crews take measurements and observations of the fissure 8 cone, in the Leilani Estates subdivision. Today, occasional bursts of spatter splashed over south rim of the cone, sending spatter down south flank of the cone almost to its base.

Then and now. It has proven difficult to exactly match past and present views of Kīlauea's summit to show the dramatic changes in the volcanic landscape, but here's our latest attempt. At left is a photo taken on November 28, 2008, with a distinct gas plume rising from the vent that had opened within Halema‘uma‘u about eight months earlier.
