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).

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.

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

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.

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.

This animated GIF shows a sequence of radar amplitude images that were acquired by the Italian Space Agency's Cosmo-SkyMed satellite system. The series shows changes to the caldera area of Kīlauea Volcano that occurred over May 5 at 6:12 a.m. HST, May 17 at 6:12 a.m. HST, and May 21 at 6:12 a.m. HST.

This thermal map shows the fissure system and lava flows as of 12:15 pm on Monday, May 21. The primary lava flows originate from the Fissure 20-22 area. The dominant ocean entry is marked. The black and white area is the extent of the thermal map.

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.

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

This thermal map shows the fissure system and lava flows as of 12:15 pm on Saturday, May 19. The two primary lava flows originate from the Fissure 20-22 area, and crossed Pohoiki Road over the past day. The flow front position based on a 6:40 pm update is shown by the red circle. The black and white area is the extent of the thermal map.

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.
