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

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.

Many are slow moving, do not avoid roads, and are simply too small for drivers to see and avoid. During rains many amphibians travel long distances regardless of the presence of intersecting roadways.

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.

This close-up image (5000x magnification) of a Kīlauea volcanic ash sample collected on May 23, 2018, was captured by a scanning electron microscope. Visible on the ash surface are tiny salt crystals that can be leached from the ash. Most of the salts in this image are aluminum sodium sulfate and calcium sulfate.

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.
