Another telephoto view of the Airborne Electromagnetic and Magnetic (AEM) survey, taken as the helicopter traversed over Halema‘uma‘u crater floor, at Kīlauea summit. This photo was taken from Uēkahuna overlook within Hawai‘i Volcanoes National Park, and helicopter and loop are visible in the center left of the image.

This morning, July 28, the USGS-Hawaiian Volcano Observatory flew the Airborne Electromagnetic and Magnetic (AEM) survey over Kaluapele—Kīlauea summit caldera—within Hawai‘i Volcanoes National Park. A helicopter flew about 120-175 ft above the ground in a grid-like pattern with a 40-ft horizontal loop suspended 35 ft below it.

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.

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.

A closer view of active lava on the north margin of Halema‘uma‘u crater, at Kīlauea summit. 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.
