Helicopter overflight of the southeast coast of the Puna district during the early morning hours of May 19, 2018. Flows are moving downslope toward the ocean. Photograph courtesy of the Hawai`i County Fire Department.

Channelized lava emerges from the elongated fissure 16-20 (in the upper right). Photo taken May 19, 2018, at 8:18 AM HST.

Channelized lava flows originate from a merged elongated fountaining source between fissures 16 and 20 in Kīlauea Volcano's lower East Rift Zone.

Fissure 18 generated a channelized lava flow that had advanced about 1 km (0.6 mi) along the west side of fissure 17 as of about noon today.

This image, captured during an HVO overflight around noon today, shows a lava flowthat crossed Pohoiki Road earlier.

Closer view of fissure 17 (middle photo) and fissure 18 (left side photo) during this morning's overflight of the area. View is toward the south.

View of the fissure system in Leilani Estates looking southwest (uprift). Fissure 17 is the lava fountain at bottom of photo, estimated to be about 50 m (164 ft) high with occasional bursts to about 100 m high (328 ft).

This morning, the line of fountains on fissure 17 coalesced into a large fountain that was sending lava 50 meters (164 feet) into the air, with small bits of spatter thrown up to 100 meters (328 feet) high. At about 12:00 p.m. HST, HVO geologists flying over the area reported that fissure 17 was going strong

These radar amplitude images were acquired by the Italian Space Agency's Cosmo-SkyMed satellite system and show changes to the caldera area of Kīlauea Volcano that occurred between May 5 at 6:12 a.m. HST (left) and May 17 at 6:12 a.m. HST (right).

A view of Halemaʻumaʻu from within the USGS Hawaiian Volcano Observatory tower at the Uēkahuna bluff in Hawaiʻi Volcanoes National Park. The tower, which has been removed, provided views of Kaluapele (Kīlauea's summit caldera), the upper portion of the rift zones, and Mauna Loa. USGS photo taken on May 18, 2018.

Lava from fissure 15 also covered the Pohiki water line.

Aerial view of the lowermost section of the active fissure system during an overflight early this morning. The view is looking toward the south; note ocean at top of photo. Fissure 17 is the on the left-hand side of photo; fissure 18 is in the middle; and fissure 20 are the two low fountaining areas in the middle right of photo.

Map as of 1:00 pm HST, May 18. Shaded purple areas indicate lava flows erupted in 1840, 1955, 1960, and 2014-2015.

HVO geologist next to cracks on Nohea Street in Leilani Estates this morning. These cracks expanded significantly in the past day. Note the vertical offset across the cracks.

Aerial view of ground cracks on Pohoiki Road during an overflight of the eruptive fissurearea at about 7 a.m. HST. Cracks continued to open and widen, some with horizontal and vertical offsets, in the area during the past 24 hours.

Large cracks run through Leilani Avenue near the old junction with Pohoiki Road. Lava spatter from fissure 6 (out of view on the left) covers the road and volcanic gas rises from cracks in the ground. This area was covered by lava from renewed fissure 6 activity on May 20. USGS photo taken by L. DeSmither on May 17, 2018.

At about 07:00 a.m. HST, Fissure 17 as shown from the air. The HVO field crew reported that the spattering height and intensity at Fissure 17 seemed to have intensified slightly from yesterday, but the length of active spattering in the fissure is shorter.

Radar image of the May 17, 2018 eruption of ash from Halema‘uma‘u Crater. This image is a slice through the cloud at an altitude of 14,000 ft (4 km) above sea level at 4:12 a.m., HST. The colors scale is radar reflectivity, a measure of the size of the particles and their concentration within the ash cloud.

The Fissure 17 flow front has slowed substantially with only small amounts of pasty "toothpaste" lava oozing out from the flow front. However lava continues to be erupted from the active fissure.

View uprift from the Hawaiian Volcano Observatory overflight this morning at 8:25 a.m. Note sulfur dioxide plumes rising from the fissures along the rift and accumulating in the cloud deck. Winds are calm today.
