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.

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.

This video was filmed on May 21, 2018, with a UAV (unmanned aerial vehicle). Limited UAV flights above the hazardous Kīlauea summit area, which is currently too dangerous for geologists to enter for ground observations, are conducted with permission from the National Park Service.

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

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.

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.
