This photo from June 25 shows the established lava channel at 6:49 pm HST, hours after the firehose activity. Today (June 26) HVO observers did not see any active surface breakouts on the delta and the channel has tubed over, but some narrow streams of lava were spilling into the ocean.

This map shows recent changes to Kīlauea's East Rift Zone lava flow field. The area of the active flow field as of May 31 is shown in pink, while widening and advancement of the active flow as of June 21 is shown in red. Older Pu‘u ‘Ō‘ō lava flows (1983-2016) are shown in gray. The yellow line is the trace of the active lava tube (dashed where uncertain).

Thermal images collected during the overflight on Wednesday, June 21, show a hot crack spanning much of the width of the lava delta at the Kamokuna ocean entry. These cracks are common on lava deltas, and suggest sagging and instability at the front of the delta.

On June 13 at about 6:00 am, there was a new pāhoehoe breakout along the episode 61g tube system approximately 1.1 km (0.7 miles) from the vent. Today (June 21), geologists visiting the site found that the ground had been cracked and uplifted about 2 m (6.6 feet) where the breakout originated (center).

The ocean entry remains active and continues to increase the size of the Kamokuna lava delta. Today, activity was concentrated towards the western side of the delta (left center), and building outward in a narrow lobe. Surface flows on the delta over the past few weeks have covered most of the delta with new lava.

Time-averaged image, or “timex,” created by averaging the intensity of light recorded at each spot, or “pixel,” during a 17-minute video taken at Madeira Beach, Florida, on June 20, 2017. Blurred white bands show where waves are breaking. Offshore band shows location of a sand bar.

“Variance” image produced from video shot at Madeira Beach, Florida, on June 20, 2017. The more the light intensity changes at a given spot, or “pixel,” during the video, the brighter the value assigned to that pixel. Motion tends to produce changes in light intensity. Note bright bands parallel to shore where waves were breaking.

The episode 61g flow continues to enter the ocean and build the delta at the Kamokuna ocean entry. Small streams of lava along the front of the delta interact with the ocean and produce a large steam plume and occasional littoral bursts.

The scattered breakouts that have been active on the steep part of the pali and at the base over the past few weeks were not visible this afternoon. The recent surface breakouts (pictured) were still warm, but no longer actively flowing.

A masked Tim Orr, on his last day of field work as a USGS Hawaiian Volcano Observatory geologist, collected a sample from Kīlauea Volcano's active lava flow on May 31, 2017. The face mask and heavy glove on his left hand provide protection from the intense radiant heat of molten lava.

In 2017, the massive Mud Creek landslide buried a quarter-mile of the famous coastal route, California’s Highway 1, with rocks and dirt more than 65 feet deep. USGS monitors erosion along the landslide-prone cliffs of Big Sur, collecting aerial photos frequently throughout the year.

This satellite image was captured on Friday, June 2, by the Sentinel-2 satellite operated by the European Space Agency. Although this is a false-color image, the color map has been chosen to mimic what the human eye would expect to see. Bright red pixels depict areas of very high temperatures and show active lava. White areas are clouds.

USGS Hawaiian Volcano Observatory broadband-seismic stations located at the summit of Kīlauea have been significantly upgraded over the past three years. During the upgrades, HVO field engineers (inset) complete the wiring connections of the solar power and telemetry systems at each site, which are about 10 m (33 ft) from the seismometer.
