Lava enters the ocean in the vicinity of Vacationland at 7 a.m. HST. The ocean entry produces a white plume called "laze," which drifts downwind. Laze is composed of steam, hydrochloric acid and tiny volcanic glass particles, which can irritate the lungs, eyes and skin.

Kīlauea Volcano — Ocean Entry Near Vacationland
Lava entering the ocean in the vicinity of Kapoho Bay is forming a lava delta, as seen from the air during this morning's overflight at about 7:00 a.m. HST.

Kīlauea Volcano — Satellite Radar of Crater Slumping
This animated GIF shows a sequence of radar amplitude images that were acquired by the Italian Space Agency's Cosmo-SkyMed satellite system. The images illustrate changes to the caldera area of Kīlauea Volcano that occurred between May 5 and June 6 at 6:00 a.m. HST.

Kīlauea LERZ lava flows and fissures, June 6, 12:00 p.m.
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.

Kīlauea Volcano — Kapoho Beach Lots
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.

Kīlauea Volcano — Lava Delta at Kapoho Bay
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.

lava is rapidly advancing through communities
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.

Kīlauea Volcano — Lava Fountaining
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.
