Map as of 10:00 a.m. HST, June 5, 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.

Morning view of Halema'uma'u and the Kīlauea Caldera from the Kīlauea overlook. Heavy steam dominates the view, and strong winds are blowing the plume to the southwest.

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.

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.

A nodal seismometer can be easily deployed for a month in a closely spaced array of tens of instruments. Arrays have been installed at Yellowstone National Park to map subsurface of geyser basins.

What a difference four days makes! These thermal images of fissure 8 fountains erupting on Kīlauea's lower East Rift Zone show a few things: 1) The lava fountains have gained height—with the tallest one growing from 150 ft to over 250 ft. 2) A pu‘u (cone) has built up downwind. 3) The amount of material wafting downwind is greater.

View of ongoing rockfalls on the southern walls of the summit crater and ground cracks just to the north of Halema‘uma‘u.

Bright image: the brightest pixel values throughout the video, useful for identifying the position of maximum wave run-up on the beach, position of all breaking waves, and sea-state.

Dark image: the darkest pixel values throughout the video, useful for tracking sediment plumes, tracking floating debris, and filtering out breaking waves.

Timex (time-exposure) image: a time-averaged image of all frames, smoothing away surface waves and determining the location of persistent wave-breaking (indicative of shallow sandbars).

Variance image: the standard deviation of pixel intensity throughout the video, and it is useful for determining how much variation or movement is occurring at a given location.
