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

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).

Lava from fissure 15 also covered the Pohiki water line.

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).

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

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.

Spattering at Fissure 17 around 12:30 AM HST, on May 18, 2018. The audio is the sound generated by the jetting of magma and gases from the fissure.

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 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

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.

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.

Video: For the past several days, intermittent small explosions have occurred at the west end of Fissure 17. These explosions throw large pieces of spatter to a height of about 150 m (500 ft).

At 7:45 a.m. HST, only traces of ash (dark areas on white rail) remain on this fence in the Volcano Golf and Country Club Subdivsion, located 4 km (2.5 mi) from the Overlook crater in Hawai‘i Volcanoes National Park.

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.

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.

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. This lava appears to be accumulating within the flow and has widened the flow margins slightly.
