Ocean entry photograph from Civil Air Patrol (CAP) overflight taken at about 12:50PM. CAP operates to support the mission of both the USGS HVO and the Hawaii County Civil Defense. Hard to discern here, but there are two entries. The coastal area spanning the entry is about 1 km (0.6 mi) wide with an about 250 m (0.15 mi) Kīpuka separating the two.

A plume rises from the site of the lava ocean entry, viewed on approach by HVO scientists during an overflight of Kīlauea Volcano's lower East Rift Zone on May 20, 2018, around 6:45 AM HST.

Lava fountains erupting from fissure 22 (center) with heavy degassing (upper right) during Kīlauea's lower East Rift Zone eruption in 2018. A narrow channelized lava flow from the fissure drains into a large, pre-existing ground crack. Weak spattering from the fissure 20 vent is visible just beyond to two sources of fissure 22 fountaining.

Late last night, the fissure 20 lava flow reached the ocean.

Video of a slow moving lava flow in Kīlauea Volcano's lower East Rift Zone, taken May 20, 2018, at around 2:31 AM HST. The flow is ~3 m (9 ft) high. The HVO scientist mapping the flow is about ~15 m (50 ft) away from the flow front. The audio is the sound of burning vegetation and the call of coqui frogs.

Helicopter overflight of Kīlauea Volcano's lower East Rift zone on May 19, 2018, around 8:18 AM, HST. ‘A‘ā lava flows emerging from the elongated fissure 16-20 form channels. The flow direction in this picture is from upper center to the lower left.

Map as of 10:00 am HST, May 19. Shaded purple areas indicate lava flows erupted in 1840, 1955, 1960, and 2014-2015. (see large map).

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

Lava fountains from Fissure 20 cover residential neighborhoods and farmland in Kīlauea Volcano's lower East Rift Zone (Hawaii). The USGS Hawaiian Volcano Observatory tracked eruptive activity and provided updates to emergency officials. Photo taken May 19, 2018, by Elise Rumpf.

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.

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

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.
