A pulse of ash rises from Halema‘uma‘u as part of semi-continuous emissions at Kīlauea's summit today. Ash can be seen falling from the plume as it is blown downwind in this image, taken around 3:28 p.m. HST.

Helicopter overflight of Kīlauea Volcano's lower East Rift Zone shows the lava channel emerging from Fissure 22 (not visible, but to the center, far right of the image). The lava is flowing downhill, from right to left in the photo.

Map as of 12:00 p.m. HST, May 23. On the main map, light purple areas indicate lava flows erupted in 1840, 1955, 1960, and 2014-2015. On the inset map (lower right), the dark purple area indicates locations of Kīlauea Volcano's East Rift Zone, Southwest Rift Zone, and summit, and the light purple area indicates the extent of Kīlauea.

Multiple explosions at Kīlauea's summit occurred throughout today, with some of the ash plumes rising 6,000 to 7,000 feet above sea level. HVO scientists keeping tabs on the explosions from a safe distance captured these images. This photo was taken at 10:36 a.m. HST. 

On Wednesday, May 23, the Hilo Civil Air Patrol conducted flights over the lower East Rift Zone eruption to assist USGS and Hawai‘i County Civil Defense Agency as they respond to the Kīlauea eruption. This image shows the scale of the lava channels feeding the ocean entries.

On May 23, 2018, the Hilo Civil Air Patrol captured this evening photograph of the coastline where lava flows are entering the sea. There are currently three primary ocean entry points, which have evolved over the course of the eruption.

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.

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.

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

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.

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.

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

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.
