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.

The fissure complex remains active in Kīlauea Volcano's lower East Rift Zone. At times, fountaining at Fissure 22 reached a height of about 50 m (about 160 ft).

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

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.

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

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).

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.

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.

After a successful beach survey and installation of remote-sensing cameras on a nearby island, scientists Shawn Harrison and Andrew Stevens spotted this bald eagle near the mouth of the Skagit River, Washington.

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.

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 Fissure 20 complex is entering the ocean in two locations, separated by an area tens of yards wide. At the time of this early morning photo, lava flowing into the ocean entry on the eastern (left-most) lobe was diminishing while lava flowing into the ocean on the western (right-most) lobe was vigorous.
