A view of the crusted over lava lake within Halema‘uma‘u at Kīlauea summit

Kīlauea summit on June 8, 2021

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). USGS photo taken

Routine overflight of Halema`uma`u crater

The eruption in Halema`uma`u crater, at the summit of Kilauea, is no longer active. The lava lake that was active between December 2020 and May 2021 remains solidified at the surface. A routine summit overflight observed no signs of residual incandescence in cracks, and only a diffuse gas plume rising from the northern portion of the lake.

Kīlauea summit on June 8, 2021

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. USGS

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. With permission from the

UAS photo of the inactive western fissure — Halema‘uma‘u, June 3, 2021

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. For scale, the tallest parts of the western

UAS view into inactive western fissure — Halema‘uma‘u, June 3, 2021

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. As evidenced by the darkness within the opening

Halema‘uma‘u crater at dusk on June 2

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. Degassing from the west vent was minimal, with most outgassing now observed coming from a location along the the crater

Halema‘uma‘u lava lake depth compared to Empire State Building

On September 29, 2021, fissure vents opened in Halema‘uma‘u crater. A new lava lake began to form on the one previously active from December 2020–May 2021. How much lava has filled Halema‘uma‘u crater?  If the Empire State Building, in New York City, was placed at the bottom of Halema‘uma‘u crater, we estimate the lava lake level could already be as high as the 70th floor

Annual Mauna Loa GPS Survey—2021

GPS campaign survey stations high on the flanks of Mauna Loa offer expansive views of neighboring volcanoes. From this station located west of Mauna Loa summit, Hualālai volcano is visible. Most Mauna Loa GPS campaign survey sites have been occupied every year since 1996, whereas less active volcanoes Hualālai and Haleakalā are surveyed every 3–5 years. USGS photo by S.

Major earthquakes cannot be predicted. Successful earthquake predictions need to have three things correct: the location, the time, and the magnitude. The best anyone can reliably do is get two out of three correct. And the most important thing for everyone to do is prepare—have a plan, build a kit, and practice drills. Join us for the ShakeOut on October 15th!

Residents on the Island of Hawaiʻi are accustomed to feeling earthquakes. As the ground shaking subsides and the safety of everyone around is assured, one of the first questions we typically ask is “how big was that earthquake?”

Last year at Kīlauea Volcano, water appeared within the summit caldera where a lava lake had been for the previous decade. This piece covers the reliance on Unoccupied Aircraft Systems (UAS) for sampling the lake water, the growth and significance of the new water lake, and implications for future eruptive activity at Kīlauea's summit.
