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.

Smithsonian Institution Global Volcanism Program map showing the 48 volcanoes that were in a continuing eruption status as of March 17, 2022. "Continuing" does not always mean persistent daily activity but indicates at least intermittent eruptive events without a break of 3 months or more.

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.

A helicopter overflight on March 17, 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 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 Halema‘uma‘u and a diffuse plume rising above Kīlauea caldera.

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 small bridge of lava 3 meters (10 feet) in height is left behind during a lull in activity within Halema‘uma‘u crater at Kīlauea's summit. The repeated ebb and flow of lava into the active lake surface has caused the pond behind this feature to start pinching off from the main part of the active lake that fills with lava when activity is more vigorous.

Telephoto view, looking east, of the lava source area for the active lava lake within Halema‘uma‘u at the summit of Kīlauea on March 11. The is supplied from the embayment which is just north (left) of the remnants of west cone area (center and right).

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.

Telephoto view looking east of the active lava lake within Halema‘uma‘u crater at the summit of Kīlauea on March 11, 2022. The craggy remains of the west vent cone, which has broken down over the past few weeks, are visible through the volcanic gas plume in the lower right.

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.

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.

The ongoing eruption in Halema‘uma‘u, at Kīlauea summit, is occurring from a number of vents in a complex located in the western half of the crater. The tallest cone in this complex measures about 19 meters (60 feet) in height and is shown in this photograph. USGS photo by L. Gallant.

Telephoto view of the distal (east) margin of the active lava lake within Halema‘uma‘u crater at the summit of Kīlauea. Minor spattering is visible along the margin, as well as two zones of crustal foundering (a process in which more cool and dense crust at the surface sinks into the molten material below).
