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.

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.

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.

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.

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.

The activity in the summit lava lake in Halema‘uma‘u has been typical in recent weeks, with the normal fluctuations in lava level. The low sun angle during the late afternoon provided good views of the different surface textures on the lake.

Subtle folds are common on the lake surface, suggesting that the crust on the lake surface is thin and flexible. In addition, small "blisters" cover large portions of the lake surface. HVO geologists have seen these blisters form, and they appear to be small bubbles that rise and push up the thin crust, without breaking it.

A view of the northern Overlook crater wall, through passing fume. The lake surface (lower left in photo) was about 22 meters (72 feet) below the crater rim (upper right in photo). The uppermost section of the crater wall is formed by stacks of thin overflows from mid-2015.
