This overview photograph of the Halema‘uma‘u eruption at the summit of Kīlauea was captured by a HVO geologist in the morning of August 24, 2022, from the webcam site on the west rim of the crater.

This reference map depicts the ongoing Kīlauea summit eruption on August 18, 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.

A helicopter overflight on August 16, 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.

This reference map depicts the ongoing Kīlauea summit eruption on August 8, 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.

KWcam image taken on August 5, 2022, just after 9:30 a.m. HST. This image shows the ongoing eruption within Halemaʻumaʻu crater at the summit of Kīlauea. The eruption began the afternoon of September 29, 2021, as fissures in the floor of the crater; this activity is generating a lava lake that is slowly filling the crater.

Uncrewed aircraft systems (UAS) flights on August 4, 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.

Telephoto view of the active lava lake within Halema‘uma‘u, at the summit of Kīlauea. During an eruption monitoring shift on July 29, 2022, spattering was observed along the eastern margin of the active lake. Additionally, crustal plates (darker pieces within the silvery active lava lake) were observed forming and breaking apart. USGS photo by J.M. Chang.

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 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.

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.
