Photo of Halema‘uma‘u, at the summit of Kīlauea, taken on July 29, 2022, from the southwest rim. Abundant fumes can be seen coming from the west vent, on the far left side of the photo. The west vent continues to feed the active lava lake, which is the silver-colored area to the east (right) of the west vent. USGS photo by J.M. Chang.

This map shows the location of the Wahapele vent (star) and lava flow (red) on Hualālai volcano. The approximate boundary between Hualālai and Mauna Loa is indicted by a dashed line. The lava flow extends 2 kilometers (1.25 miles) farther into the ocean.

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.

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.

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.
