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.

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.

This reference map depicts the ongoing Kīlauea summit eruption on March 4, 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.

At approximately 8:15 a.m. on March 2, 2022, HVO geologists conducted an overflight of Kīlauea's summit. The eruption, which resumed several hours earlier, at approximately 1 a.m., continues within Halema‘uma‘u crater. In this photo, active lava is visible near the west vent, near the center of the image, and Mauna Loa looms in the background. USGS image by F.

This telephoto view, taken during a eruption monitoring overflight of Kīlauea summit on March 2, 2022, shows the west vent area within Halema‘uma‘u crater. Lava erupts from multiple locations near where the west vent cone, which has broken down over the past several weeks, was located.

A helicopter overflight on March 2, 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.

Summit tiltmeter data (green) shown against lava lake level (blue). The top panel is for the time period 12/1/2017–1/30/2018 and is representative of the “old” lava lake. For this panel, lake level was retrieved from thermal camera images, hence it is given in units of “pixels.” The bottom panel is from 1/15/2022–2/15/2022; in this case, the lake l

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).

Telephoto view taken on March 2, 2022, during an overflight of Halema‘uma‘u crater at the summit of Kīlauea volcano. In the center of the image, one of the spatter cones that has developed on the surface of the crater floor in recent weeks is visible.

During a routine eruption-monitoring overflight of Kīlauea's summit, Hawaiian Volcano Observatory geologists captured this view of the south caldera area. Bulldozers were used to create mounds, visible in the right center portion of the image, in an effort to prevent planes from landing in this area of Kīlauea during World War II. USGS image by F. Trusdell.

A portion of Crater Rim Drive that was damaged during Kīlauea's 2018 summit collapse events was visible during a Hawaiian Volcano Observatory monitoring overflight on March 2, 2022. Crater Rim Drive used to go around Kīlauea summit caldera within Hawai‘i Volcanoes National Park.
