Kīlauea LERZ Fissures and Flows, June 1, 6:00 p.m.
Kīlauea LERZ Fissures and Flows, June 1, 6:00 p.m.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.

Scientists on the early morning overflight of Kīlauea Volcano's lower East Rift Zone documented a very weak ocean entry. For the easternmost lobe, only a few small finger channels of lava were entering the ocean.

Tephra (airborne lava fragments) erupted by the high lava fountains of fissure 8 was carried downwind, where the frothy rock fragments fell on Leilani Street, just past Kupono Street, in the Leilani Estates subdivision.
