 Fissure 8 lava fountain heights fluctuated between about 40 m (130 ft) and 70 m (230 ft) during this morning's overflight at about 6:30 a.m. HST.

Many large blocks appeared to be in depressions in the ash, but upon closer examination, it was concluded that wind had winnowed ash from around the blocks, creating a false impression that the depressions were made by impact.

Crack on Crater Rim Drive just east of the parking lot, with the National Park sign indicating "Halema‘uma‘u" at right. This crack shows 42 cm (16.5 in) of right lateral offset—as measured by fitting the center stripe on the road back together)—and was about 25 cm (10 in) wide.

With careful consideration and planning to avoid ongoing volcanic hazards as much as possible, an HVO scientist who has been studying the behavior of Kīlauea's summit for decades, briefly visited the parking area for the former Halema‘uma‘u overlook (closed since 2008) on June 5 to make direct observations of and gather data from the effects of recent explosions wit

The Halema‘uma‘u parking lot is sliced into blocks by cracks. These cracks, first noted in a very early stage on May 13, now are the dominant features of the parking lot. The cracks, which are circumferential to Halema‘uma‘u, warp and offset the pavement and curbing, as seen here. The crack responsible for warping this curbstone is visible on both sides of it.

On June 6, at 4:07 p.m. HST, an explosion within Halema‘uma‘u sent an ash and gas plume to a height of about 10,000 feet above sea level. The explosion released energy equivalent to that of a magnitude-5.6 earthquake; a result of the explosion-related energy release was ground shaking felt throughout the summit area.

On June 6, at 4:07 p.m. HST, an explosion within Halema‘uma‘u sent an ash and gas plume to a height of about 10,000 feet above sea level.

The vigorous lava fountain at Fissure 8 reached heights of 45 m (150 ft) as shown in this image taken around 9:30 AM.

How do you keep people safe when lava is rapidly advancing through communities? This was just one of the topics addressed during the Cities on Volcanoes 10 meeting in Naples, Italy, last week. Lava flows recently erupted from Kīlauea Volcano's lower East Rift Zone inundated hundreds of homes in the lower Puna District of Hawai‘i Island.

This view, looking south at Kīlauea's lower East Rift Zone, was captured during HVO's 6:00 a.m. HST helicopter overflight today.

This fish-eye view of the lava delta filling the former Kapoho Bay shows that while the delta margin nearest the ocean has cooled somewhat, the lava flow front is still very hot and producing laze (lava haze). Laze is a local hazard composed of acidic gases and volcanic glass fragments and should be avoided.

A robust laze (lava haze) plume rises from the northern side of the fissure 8 lava flow margins in the former Kapoho Bay.

Map as of 12:00 p.m. (noon) HST, June 6, 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.

Views from HVO's helicopter overflight at 1PM HST, show the remains of the Kapoho Beach Lots subdivision and the fissure 8 flow front. The northern flow margin in this area was unchanged from HVO's morning flight and appeared to have stopped advancing at the time of the flight.

Lava fountaining continues at fissure 8, although overnight crews reported reduced heights of 40-50 m (130-164 ft). The fountain has built a 35 m (115 ft) high cone, and an actively-growing spatter rampart on its eastern side.

HVO scientists captured this aerial view of a much-changed Halema‘uma‘u during their overflight of the summit this afternoon.

As of the morning of June 5, the fissure 8 lava flow front had completely filled Kapoho Bay.
