An aerial view of Halema‘uma‘u at the summit of Kīlauea Volcano captured from an Unmanned Aircraft Systems (UAS) overflight video on May 31, 2018. Limited UAS flights into this hazardous area are conducted with permission and coordination with Hawai‘i Volcanoes National Park to collect visual information on this changing eruption site.

Lava from fissure 18 travels to the southeast (lower left of photo). The flow front that had approached the ocean yesterday has stalled. This view is looking uprift, with fissure 8 in the distance (upper right of photo).

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.

Map as of 9:00 a.m. HST, May 31, 2018. Given the dynamic nature of Kīlauea 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.

Lava flow erupted from fissure 8, photographed during HVO's early morning overflight today.

Views Kīlauea's summit were often obscured by fog and rain today, but a break in the weather around 2:00 p.m. HST allowed HVO's webcam to capture this image of the gas and steam plume being emitted from Halema‘uma‘u.

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—and could have changed rapidly since that time.

Fissure 8 reactivated on the afternoon of May 28, when, at times, lava fountains were reaching heights of 200 feet and feeding a lava flow&

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.

This animated GIF shows a sequence of radar amplitude images that were acquired by the Italian Space Agency's Cosmo-SkyMed satellite system. The series shows changes to the caldera area of Kīlauea Volcano that occurred over May 5 at 6:12 a.m. HST, May 17 at 6:12 a.m.

View of the fissure complex looking toward the southwest (uprift) during this afternoon's overflight at about 1:15 p.m. HST. The small lava flows spreading to the southeast from the fissure complex (lower middle) originate in the area of between fissures 16 and 18.

View of the fissurecomplex is toward the southeast during this afternoon's overflight of the lower East Rift Zone at about 1:15 p.m. HST. The lava channel in middle of photograph is filling with lava erupted from fissure 22.

Close view of lava channel in middle of the lava flow erupting from fissure 8 during this morning's overflight at about 7 a.m. HST. The tallest lava fountain is fissure 8, active since yesterday evening. The eruption rate at fissure 8 diminished significantly later in the morning.
