Aerial view of the ocean-entry areas at about 12:30 p.m. HST. Lava flowing into the ocean diminished overnight and this morning (note lack of obvious plume at the entry areas). View is toward the northwest. 

This image shows radar data acquired by the European Space Agency's Sentinel-1 satellite over Kīlauea Volcano on May 19 at 6:30 PM HST (left) compared to May 25 at 6:30 PM HST (right). The satellite transmits a radar signal toward the surface and measures the strength of the return, with bright areas indicating a strong return and dark areas a weak return.

This ‘a‘ā flow, erupted from fissures 7 and 21, was approximately 3–4 meters (yards) high at the flow front and slowly advancing to the northeast in the Leilani Estates subdivision around 10:30 a.m. HST today.

An aerial view, looking west, of the two active ocean entries on Kīlauea Volcano's lower East Rift Zone. The large white plume (foreground) is the eastern ocean entry; the weaker, western plume can be seen in the distance.

Aerial view of fissure 22 looking toward the south. Fissure 22 continues to erupt lava that is flowing southeast to the coast and entering the ocean.

This thermal map shows the fissure system and lava flows as of 12:15 pm on Friday, May 25. Two channelized lava flows are reaching the ocean. In addition, a lava flow is active in Leilani Estates subdivision, near Fissure 7.

Aerial view of the active ocean entries at Kīlauea Volcano's lower East Rift Zone captured during this morning's HVO overflight. An ongoing hazard at the ocean entries is laze.

Fissures 6 (left) and 13 (right), with lava flows merging into one channel that flows into the ocean at the western-most entry. Note plume in distance at the ocean entries (top left). Photo is from an overflight at mid day.

Map as of 2:00 p.m. HST, May 25. Shaded purple areas indicate lava flows erupted in 1840, 1955, 1960, and 2014-2015.

Activity at fissure 6 this morning (May 25, 2018). Lava fountains have built a small spatter cone (black mound) from which lava was spilling out onto the surface and flowing into a small po

During HVO's overflight this morning, the fissure 22 fountain was not as high as several days ago, but was still erupting significant lava.

This thermal map shows the fissure system and lava flows as of 12:15 pm on Thursday, May 24. Two channelized lava flows are reaching the ocean. In addition, a new lava flow is active in Leilani Estates subdivision, near Fissure 7. The black and white area is the extent of the thermal map.

Blue arrows indicate contraction across the upper and middle rift zone as magma withdrew from this area and moved down the rift zone beginning on April 30, 2018. Black arrows indicate expansion across the rift zone as magma intruded into the LERZ; the area stopped widening on about May 18.

Poor weather at the summit of Kīlauea has obscured views of Halema‘uma‘u for much of today, but a brief break in the weather around noon allowed HVO's webcam to capture this image of an ash plume rising from the crater at 12:17 p.m. HST.

During today's overflight of the ongoing lower East Rift Zone eruption, HVO geologists noted that fissures 6, 13 and 22 were still erupting, with two channelized flows reaching the ocean. The eastern lava channel splits just before reaching the ocean, so it has two entry points, creating a total of three ocean entries on the flow field.
