Viewed from the intersection of Nohea and Leilani Streets at 10:15AM HST on June 1, the Fissure 8 lava fountain (to the right) appears to have decreased in height from previous sustained heights of 260 feet.

Fissure 8 continues to feed lava into multiple flow lobes. One lobe is advancing through agricultural lands toward the northeast, as shown in this image taken from a helicopter overflight on June 1, 2018, at 6:21 AM.

Map as of 6:00 p.m. HST, June 1, 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.

Crews make visual observations of activity at fissure 8 around 5:30 a.m. HST. Fountain heights this morning continue to reach 70 to 80 m (230 to 260 ft) above ground level.

Helicopter overflight shows advancing lobes from fissure 8 (fissure 8 is not pictured but located to the right, out of view). Advance rates were less than 100 yards per hour for the three lobes of the flow, as measured during the overnight hours.
