Telephoto image of the Airborne Electromagnetic and Magnetic (AEM) survey helicopter and hoop flying over Kīlauea caldera on July 28, 2022.

A view of the Airborne Electromagnetic and Magnetic (AEM) survey over Kaluapele—Kīlauea summit caldera—taken from Uēkahuna overlook in Hawai‘i Volcanoes National Park. The loop system below the helicopter transmits weak, low-frequency radio waves into the ground and measures the Earth response as well as passively detects variations in the Earth’s magnetic field.

During the survey, which is funded by the Additional Supplemental Appropriations for Disaster Relief Act of 2019 (H.R. 2157), the helicopter flew about 150 feet above the ground.

This reference map depicts the ongoing Kīlauea summit eruption on July 22, 2022. One eruptive vent (orange) is active within Halema‘uma‘u, on the western side of the crater floor. An adjacent pond (purple) is feeding lava to a larger lake (red) via a crusted-over tube. The eruption statistics provided here are current as of the last HVO overflight on July 19, 2022.

Aerial view of the north wall of Kīlauea caldera. The bright green area near the center of the image is the Volcano Golf Course. Between it and the caldera edge is the Kīlauea Military Camp.

During a Hawaiian Volcano Observatory Kīlauea summit monitoring overflight on July 19, 2022, lava was oozing out the northern edge of Halema‘uma‘u crater floor. Incandescent lava is visible in this area, near the bottom center of this image, where lava is slowly encroaching on the large down-dropped block that formed during the 2018 caldera collapse.

This small pad of lava oozed out from the crater floor along the north boundary of the crater, near where the down-dropped block to the east slopes down towards Halema‘uma‘u crater. USGS image by K. Mulliken. 

An aerial image of the western portion of Halema‘uma‘u crater at the summit of Kīlauea. The active lava lake within the western portion of Halema‘uma‘u crater is visible in approximately the center of the image, and lava spattering is visible along the eastern edge of the lake.

Telephoto aerial image of a hornito on the surface of the eastern part of Halema‘uma‘u crater floor at the summit of Kīlauea. In the foreground, Hawaiian Volcano Observatory monitoring equipment on the eastern rim of Halema‘uma‘u crater gives a sense of scale. Several hornitos, each several tens of feet tall, rise from the floor of Halema‘uma‘u crater.

Hawaiian Volcano Observatory geologists captured this view of the caldera at Kīlauea summit during an overflight the morning of July 19, 2022.

A helicopter overflight on July 19, 2022, allowed for aerial visual and thermal imagery to be collected of Halema‘uma‘u crater at the summit of Kīlauea. The active lake surface is limited to the western portion of the crater.

A Hawaiian Volcano Observatory scientist uses a laser rangefinder to measure the distance to different areas of interest around the crater. These measurements help us to track changes in the lava lake and crater floor, and to measure features such as the lava lake and west vent cone. USGS photo taken by L. DeSmither on July 13, 2022.

A photo of Halema‘uma‘u crater, at Kīlauea summit, taken on July 13 from the western rim of the crater. SO₂ gas emissions remain elevated and were measured at about 1250 tonnes per day on July 14. Volcanic gases, and steam from rain on the crater floor, often obscured visibility with only intermittent views of the crater floor and active lava lake.

A telephoto image of the active lava lake within Halema‘uma‘u crater, at the summit of Kīlauea, taken on July 13. During the current deflationary tilt phase of a deflation-inflation event, the active lava lake level is about 9 m (30 ft) below the lake rim. The west vent cone (lower right) is about 24 m (79 ft) tall, with a few areas that were weakly incandescent.
