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

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.

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.

Fissure 17 as seen from the air on Monday, May 17, around 7:00 a.m. HST, when the overall vigor of fissure appeared to have dropped from the previous two days. Twenty fissures have erupted in the lower Puna District on the Island of Hawai‘i as of May 17, and additional fissures could still open as this eruption on Kīlauea Volcano's East Rift Zone continues.

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.

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.

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.

Close view of rock hurled from the Overlook crater during an explosive event last evening. The rock broke apart on impact, and was about 60 cm (24 in) before it hit the ground. The location is a few hundred meters (yards) south of the Overlook crater at the Halema‘uma‘u parking lot.

Same area between fissures 16 and 20 at 9:33 a.m. By the time geologists reached the site on foot, the spattering had died down and they were only hearing gas rushing sounds.
