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.

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.

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.

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.

Sink holes (dark spots to right of large tree) are beginning to form along fractures beneath the field of tephra that has formed downwind of fissure 8.

Rockfalls occur regularly around the Kīlauea Caldera during summit collapse events. This photograph shows rocks falling from the cliffs below Uēkahuna Bluff just after the 11:55 a.m. collapse today.

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.
