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.

A closer look at Kīlauea's summit lava lake on Wednesday evening, around 6:30 p.m., when the lake was just 8 meters (26 feet) below the floor of Halema‘uma‘u Crater.

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.

View of the 61g flow field, from Pu‘u ‘Ō‘ō (visible on top, left horizon) to the westernmost ocean entry at the coast, where lava spills into the sea, creating a lava delta.

View of the lava pond within the Pu‘u ‘Ō‘ō west pit crater, which is about 50 m (164 ft) across. Weak spattering on the lava pond surface, about 23 m (75 ft) below the crater rim, is visible through the thick volcanic gas cloud.

An aerial view of a new breakout (light-colored flow at center of image) from the 61g tube. The breakout began with some vigor on the morning August 29, but today it was sluggish, with only a few scattered pāhoehoe toes still active on the margins of the flow.

Calm after the storm—a beautiful day on Kīlauea Volcano's East Rift Zone. Rain from Hurricane Madeline had little impact on Pu‘u ‘Ō‘ō, shown here, or lava flow 61g.

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.

The dark-colored charcoal (left of rock hammer) from a log buried by lava was found at the base of an ‘A‘ā flow in the District of Ka‘ū on the Island of Hawai‘i. The age of this charcoal, determined by an accelerator mass spectrometer radiocarbon method, is 2075 plus or minus 36 years before present. USGS photo.

This video clip, filmed on August 12, 2016, shows a typical pāhoehoe breakout on Kīlauea Volcano's "61g" lava flow (actual speed).

"The whole Eastern Half of the lake is in a state of continuous activity with Old Faithful playing 10 to 20 feet every 35 to 45 seconds." J.M. Lydgate wrote these words and sketched this map of Halema‘uma‘u Crater in the Volcano House Register (a collection of hotel guest comments) in July 1909 to document his observations of Kīlauea Volcano.

Kīlauea Volcano's active lava flow continues to bury more of the emergency access route (Chain of Craters Road) in Hawai‘i Volcanoes National Park. Early this morning, slow-moving breakouts were oozing across the road on the west side of the flow.

Kīlauea Volcano's older "61g" lava flows have now inflated (left side of photo), creating jagged terrain that rises as much as 3 m (10 ft) above the road. Today, new lava (right) was covering additional areas of the gravel road.

At the summit of Kīlauea, the weather cleared, but inflation turned to deflation and the lava lake level dropped, so the spattering that had been visible from overlooks in Hawai‘i Volcanoes National Park the past two days is no longer visible today. But, it was a beautiful day to view Halema‘uma‘u Crater from the Jaggar Museum Overlook!
