A telephoto image of the eastern Kamokuna lava delta (from the same location as the photo above) shows lava dribbling into the sea and a closer view of the ocean entry plume.

Under trade wind conditions, Kīlauea Volcano's eastern Kamokuna lava delta is more safely viewed from outside the closed area on the east (Kalapana) side of the ocean entry. Today, trade winds were blowing the billowy white ocean entry plume, a mixture of superheated steam, hydrochloric acid, and tiny shards of volcanic glass, away from the viewing area.

The explosive interaction of hot lava entering cool seawater throws spatter (clots of molten lava, visible at center of image) from the leading edge of the lava delta forming at Kīlauea's Kamokuna ocean entry.

Lava continues to flow into the ocean at Kamokuna, with two main entry areas, both forming lava deltas. The eastern lava delta is the larger of the two, and today, a broad span of small lava streams entering the sea was creating a wide ocean entry plume. The smaller western entry was feeding a weaker plume.

A breakout from the base of the pali, which began last week, remained active today, with scattered pāhoehoe lobes near the eastern margin of the 61g lava flow. Fume from the lava tubes on the pali can be seen in the upper left part of the image.

The lava lake at the summit of Kīlauea remained at a high level today, about 18 m (60 ft) from the floor of Halema‘uma‘u Crater at the time of this photo.

The eastern (right) lava delta is the larger of the two, with a broad span of small lava flows entering the sea creating a wide ocean entry plume. Fewer flows on the smaller western (left) entry created a weaker plume.

Lava flows into the sea at Kamokuna on the southeast coast of Kīlauea Volcano, with two main entry areas. Both entries have formed lava deltas seaward from the previous shoreline. The eastern (right-hand side) lava delta is the larger of the two—the broad span of small lava streams entering the sea created a wider ocean-entry plume.

Kīlauea's summit lava lake rose to within about 5 m (16 ft) of the floor of Halema‘uma‘u Crater this morning, before dropping back down slightly with the onset of spattering. This view, taken from the east edge of Halema‘uma‘u, shows spattering at the south corner of the lava lake.

Zoomed in view of the spattering at the south edge of the lava lake. Note the black high-lava mark from this morning on the wall just behind the spattering.

Lava continues to flow into the sea at the Kamokuna ocean entry. This photograph, taken from the eastern margin of the lava flow, shows the eastern ocean entry site and the lava delta that has formed there. Today, several small streams of incandescent lava could be seen spilling into the water, with occasional small explosive bursts occurring in the surf.

This photo, taken by Thomas Jaggar on December 21 during the1935 Mauna Loa eruption, shows the Humuula pāhoehoe flow ponding and slowly expanding eastward. The image looks east-southeast toward Pu‘uhuluhulu from the southernmost Omaokoili cinder cone in the vicinity of today's Saddle Road and Mauna Kea Access Road juncture. USGS photo.

On Wednesday evening (September 7), the lava lake at Kīlauea's summit reached a high level, about 8 m (26 feet) below the floor of Halema‘uma‘u Crater. This panorama shows the former Halema‘uma‘u Overlook (closed since 2008 due to volcanic hazards) at the far left.
