A photograph taken during a helicopter overflight on the morning of March 29, 2022, with views of Kīlauea Iki Crater (top left), Pu‘upua‘i (left), and Keanakāko‘i Crater (bottom right). Pu‘upua‘i is a large cinder cone that during the 1959 eruption of Kīlauea Iki. The trail leading to a popular viewing area for the current eruption is visible in the bottom center.

A telephoto view looking southwest taken during a helicopter overflight on the morning of March 29, 2022, of the Kamakaiʻa Hills of Kīlauea's Southwest Rift Zone. Geologic mapping efforts indicate that the Kamakaiʻa Hills likely erupted within the last 250 years. The southwest flank of Mauna Loa is faint in the distant background to the right. USGS photo by N.

Located south of Halema‘uma‘u crater, in Kīlauea south caldera region, the Keller Well is a borehole drilled in 1973 to a depth of 4,140 ft (1,262 m). Hawaii Volcano Observatory geologists measure the depth to the water table quarterly to monitor Kīlauea summit region hydrology. Photo taken on March 22, 2022, by F. Younger.

On March 22, USGS Hawaiian Volcano Observatory Scientists measured the water level in Keller Well, located in Kīlauea's south caldera region. Scientists also obtained a water sample. Keller Well is measured and sampled quarterly to monitor how magma supply to Kīlauea's summit reservoirs might impact regional ground water.

A routine helicopter overflight on March 17, 2022, provided airborne views of the summit eruption in Halema‘uma‘u crater, at the summit of Kīlauea. At the start of the video, the helicopter flies over the edge of the large collapse depression formed during the 2018 eruption.

A photograph taken during a helicopter overflight on the morning of March 17, 2022, shows an overview of Kīlauea Iki and Pu‘u Pua‘i. Pu‘u Pua‘i is a large cinder cone that formed as a result of the towering 1,900 foot (580 meters) lava fountains during the eruption of Kīlauea Iki.

This reference map depicts the ongoing Kīlauea summit eruption on March 21, 2022. One eruptive vent is intermittently active within Halema‘uma‘u, in the western end of the crater. When this vent is effusing lava, it pours into a lava lake, colored red on this map.

This 8 meter (26 feet) tall arch of lava was left behind during a lull in eruptive activity within Halema‘uma‘u crater, at Kīlauea's summit. This feature is located in the spillway that connects the vent of Halema‘uma‘u to the lava lake.

A view of Halema‘uma‘u at Kīlauea summit, looking east, on the morning of March 11. The active lava lake is silvery gray and is visible in the lower right. The remnants of the west vent cone area are visible to the west (bottom right) of the active lava lake, and are the source of the majority of bluish-white volcanic gas emissions. USGS image by N. Deligne.

Kīlauea's summit eruption continues within Halema‘uma‘u crater. A number of vents are located in the western half of the crater, where the west vent cone used to be. On March 4, 2022, the highest of these features was measured at 19 meters (60 feet) in height and is shown in this photograph. USGS photo by L. Gallant.

Bursts of lava erupting from a vent in the western half of Halema‘uma‘u crater, at Kīlauea volcano summit, were reaching 15-20 meters (50-65 feet) from the top of the cone on March 4, 2022. A small channel of sluggish lava was flowing down the western side of this cone.
