A helicopter overflight of Kīlauea Volcano's lower East Rift Zone shows the interaction of lava and seawater to produce a laze plume. Laze is formed when lava enters the ocean. The interaction sends hydrochloric acid and steam with fine glass particles into the air.

View during an early morning overflight of Kīlauea Volcano's lower East Rift Zone. Two fissures (not pictured) are sending lava down two channels that merge near the coast.

An aerial view looking downrift from Leilani Estates at erupting fissures 5, 6, 19, and 22. Ponded lava from these fissures fed lava channels moving downslope, right side of the image, including the channels that fed the ocean entries just north of MacKenzie State Park.

Solidified lava from Fissure 17 (located to the east of the currently active fissure complex) has a consistency similar to toothpaste.

The fissure complex, pictured in the upper right, continues to feed a meandering lava flow (in the center). Lava in the easternmost lobe i

Lava continues to enter the sea at two locations this morning. During this morning's overflight, the wind was blowing the "laze" plumes along the shoreline toward the southwest.

Map as of 8:00 am HST, May 21. Shaded purple areas indicate lava flows erupted in 1840, 1955, 1960, and 2014-2015.

Lava fountain at fissure 22, 9:03 a.m. HST, from the north side the fissure complex. Geologists report this morning the lava fountain as high as about 50 m (164 ft).

Aerial view of erupting fissure 22 and lava channels flowing southward from the fissure during an early morning overflight. View is toward the southwest.

By the end of the afternoon, only a single ocean entry was active. The lava channel originates from fissure 22. This photo was taken during a late afternoon overflight of the lower East Rift Zone, Kīlauea Volcano.

Helicopter overflight of Kīlauea Volcano's Lower East Rift Zone shows fountaining at Fissure 22.

The helicopter hovers above the ocean entry on May 20, 2018, around 6:45 AM HST. Several braided lava channels (red) are visible on the right. The white plume is "laze," which forms when hot lava hits the ocean sending hydrochloric acid and steam with fine glass particles into the air.

Lava flows from the Fissure 20 complex move downslope and enter the ocean. Lava can be seen in the middle of the channel. A laze plume hides the point of ocean entry.

Lava from the eastern channel of the Fissure 20 complex is flowing into a crack in the ground that opened on the morning of May 20, 2018. The crack is "robbing" the easternmost channel of lava and the eastern ocean entry is therefore less vigorous than the western entry point.

Map as of 11:00 am HST, May 20. Shaded purple areas indicate lava flows erupted in 1840, 1955, 1960, and 2014-2015. Site of active ocean entry is shown with dots.

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.

Lava from the eastern channel of the Fissure 20 complex flows into a crack in the ground. The crack opened in the early morning hours of May 20, 2018. Prior to opening, lavawas flowing vigorously down a channel. After the crack formed, the lava began pouring into the ground.

Lava from the fissure complex erupting in Kīlauea's lower East Rift Zone entered the ocean in late evening on May 19, 2018. The active ocean entry is producing a white "laze" plume. Laze is formed when hot lava hits the ocean, forming a plume of hydrochloric acid and steam with fine glass particles.

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.

Lava from the Fissure 20 complex enters the ocean generating a white laze plume. Helicopter overflight on May 20, 2018, at 6:45 AM HST.
