Kilauea volcano update: Strong lava effusion continues from fissure 8

Lava fountaining and active flow to the NE from fissure #8 at Kilauea's lower east rift zone this morning (night in Hawaii)

This view, looking south at Kīlauea's lower East Rift Zone, was captured during HVO's 6:00 a.m. HST (6 June) helicopter overflight today. It shows continued fountaining of fissure 8 and the lava flow channel fed by it. Lava continues to flow quickly in these braided channels; the flow margins are currently stable and have not experienced any breakouts since June 5. (image: HVO / USGS)
The activity in the lower east rift zone continues with no significant changes. After a brief episode of declining output of magma from fissure #8 and the contemporary reactivation and lava effusion from a number of other fissures, activity shifted back to fissure #8 which has been the main vent of the rift eruption over the past week.
Tilt at the summit with overall deflation interrupted by quick inflation "jumps" - each vertical jump corresponds to an explosion blowing out debris that has been clogging the collapsing conduit
Strong fountaining continues, with moderate heights of 150-180 ft (50-70 m), "feeding a stable channel to the east to the ocean entry in the Kapoho Bay area. Lava is entering the ocean in the Vacationland subdivision. Vacationland has been completely covered by lava, and overnight the flow expanded north by 100 m within Kapoho Beach Lots. The lava delta that formed at Kapoho Bay extended slightly overnight." (HVO / USGS)
No other fissures were active as of 6 June afternoon local time.
The slow caldera collapse (subsidence and slumping) currently observed at the central Halema'uma'u crater and in its immediate surroundings continues. Seismic activity has again been increasing after Tuesday morning's small explosion, and lead up to a new explosion that occurred a few hours ago and is visible on the deformation plot (s. attached).
Kilauea volcano update: Vigorous fountaining from fissure 8 continues, the resulting lava flow has completely filled Kapoho Bay and created a second ocean entry at Vacationland
Wednesday, Jun 06, 2018
In the Lower East Rift Zone lava effusion persists from fissure 8 which continues to feed a channel transporting lava eastward to the ocean entry in the Kapoho Bay area. HVO's Tuesday 5 June mid-day overflight showed that this flow has completely filled Kapoho Bay and formed a lava delta extending about 1.3 kilometre (0.8 miles) out from the former coastline. Meanwhile the outbreak of this flow that started to wrap around the western side of Kapoho cinder cone has completely encircled it, re-joined the wide Kapoho Bay lava flow channel but travelled south of it where it now creates a second ocean entry in the Vacationland tidepools area. The destruction of the Kapoho Bay and Vacationland neighbourhoods and beautiful recreational areas is immense as almost all of it got covered by the fissure 8 lava flow over the past 2 days. Whatever remains is still under threat as the wide fissure 8 lava flow is also still spreading sideways ... [details]

The eruption continues without significant changes: lava fountaining remains strong from fissure #8 although a bit decreased during the past day, feeding a large river of lava that flows towards the new ocean entry at Kaphoho. ... [details]

Kilauea volcano update: Lava fountaining continues at fissure 8, the resulting lava flow almost reaching the ocean at Kapoho
Monday, Jun 04, 2018
In the Lower East Rift Zone vigorous fountaining persisted from fissure 8 throughout the weekend, feeding large amounts of lava into the channel that runs northeast as the western branches of this flow became inactive during the night from Friday 1 to Saturday 2 June. The remaining fissure 8 lava flow continued to travel along Highway 132 to Kapoho and eventually crossed Highway 137 at the ‘Four Corners’ intersection of Highways 132 and 137 on Saturday morning 2 June at 9h30 am local time. It thereby effectively cut off the land south of this active flow front from Pohoiko to Vacationland Hawaii where any people that got stuck are evacuated by boat and helicopter. The same lava flow subsequently wrapped around Kapoho cinder cone and entered it through the gap on its east side, filling up the crater and creating a large steam plume as it evaporated all the water of Green Lake. As lava continues to pour into the Kapoho cinder cone in Green forest, it creates a stunning ‘lava fall’ The active flow then spread out to a 0.5 mile wide lava flow front that continues to make its way towards the ocean at Kapoho Bay. On Sunday evening 3 June 19h00 local time HVO/USGS reported that this flow front was merely 225 meter (245 yards) away from the ocean. ... [details]
