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.

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.

Compilation of three short videos from helicopter overflights of the fissure complex, in Kīlauea Volcano's lower East Rift Zone on May 22, 2018. Fissure 22 is the dominant fissure, with lava fountaining to 50 m (about 160 ft) or more in height.

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

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.

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.

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.
