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.

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.

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.

Kīlauea Volcano's lava lake within Halema‘uma‘u Crater rose steadily over the past day in concert with summit inflation. This morning, with the lake level at just 19 m (62 ft) below the summit vent rim, vigorous spattering on the lake surface was visible from the Jaggar Museum Overlook in Hawai‘i Volcanoes National Park.

This map shows recent changes to Kīlauea's East Rift Zone lava flow field at the coast. The area of the active flow field as of August 19 is shown in pink, while widening and advancement of the active flow as mapped on September 1 is shown in red. The base is a Digital Globe image from January 2016.

A closer view of where lava is entering the sea along a 1.1-km- (0.7-mi-) wide section of the coastline. There is no evidence that high surf from Hurricane Madeline had any impact on the lava deltas that have formed, and continue to grow, at the ocean entries.
