A view of Halema‘uma‘u on June 11, 2021, at 12:20 p.m. HST. Although eruptive activity has paused at the Kīlauea summit, HVO geologists still monitor the lava lake and summit area regularly. They make observations to note any physical changes in the landscape or visual changes in gas emissions.

Water flowing south and west of the divide ends up in the Pacific Ocean, whereas water north and east of the divide ends up in the Gulf of Mexico.

This rat snake is a preserved museum specimen with snake fungal disease that was collected in Tennessee in 1973. The photo was taken at the USGS National Wildlife Health Center in 2017 as part of a study.

On June 8, 2021, the USGS Hawaiian Volcano Observatory conducted a routine helicopter overflight and fieldwork at the summit of Kīlauea. Here, a geophysicist returns to the helicopter after making Global Positioning Systems (GPS) measurements. These surveys measure small changes in the ground surface caused by subsurface magma movement.

A view of the crusted over lava lake within Halema‘uma‘u at Kīlauea summit, taken during a helicopter overflight on June 8, 2021. No incandescence (red lava) has been visible on the solidified lava lake surface for over two weeks. Light degassing continues in a few areas around the margin of the lava lake, mainly along the north crater wall (bottom left).

No eruptive activity or major changes were observed during a USGS Hawaiian Volcano Observatory Kīlauea summit monitoring shift on June 8, 2021. An area near the north wall of Halema‘uma‘u continues to visibly emit gases, though the eruption has paused. The most recent sulfur dioxide emission rate, measured on June 4, remains slightly elevated at 54 tonnes per day.

Portions of Crater Rim Drive, which was damaged during the 2018 Kīlauea summit collapse, are visible from the south rim of Halema‘uma‘u. The lava lake within Halema‘uma‘u and the east wall of Halema‘uma‘u crater are visible in the background. This area of Hawai‘i Volcanoes National Park remains closed to the public due to hazardous conditions.

This close-up Unoccupied Aircraft Systems (UAS) photo of the inactive western fissure within Halema‘uma‘u was captured on Thursday, June 3, 2021, at the summit of Kīlauea. The recent pause in the eruption has allowed the USGS Hawaiian Volcano Observatory (HVO) UAS pilots to safely photograph the eruptive features from new angles.

This Unoccupied Aircraft Systems (UAS) photo, looking straight down into the inactive western fissure within Halema‘uma‘u at the summit of Kīlauea, was captured on Thursday, June 3, 2021. One of the objectives of the UAS mission was to get a close-up look into the fissure to see if any incandescent lava was still visible.

During a Kīlauea summit monitoring field shift on the evening of June 2, HVO geologists observed no eruptive activity or any major changes at the Halema‘uma‘u crater lava lake. No incandescence was visible anywhere on the lake surface or around the vents.
