On October 28, 2022, HVO geologists conducted an overflight of Mauna Loa’s summit region. This photo of Sulfur Cone, on the Southwest Rift Zone, is at an elevation of 3,430 meters (11,240 feet) above sea level. The 1950 fissure is visible in the foreground of the image. USGS image by K. Mulliken.

An overflight at approximately 8:30 a.m. on October 28, 2022, provided aerial views of Mauna Loa Volcano, which is not erupting. This video contains several clips from the overflight, shown at 2X speed. The video includes (in this order) views of the south flank, the Southwest Rift Zone, the summit caldera (Moku‘āweoweo), the Northeast Rift Zone, and the south flank.

October 28, 2022 — Kīlauea Summit Overflight

An eruption-monitoring overflight of Halema‘uma‘u, at Kīlauea's summit. This eruption began at approximately 3:20 p.m. on September 29, 2021.

A southwest-facing view of the eruption within Halema‘uma‘u, at the summit of Kīlauea. Diffuse steam and volcanic gases are emitted from the crater floor and eruption site. The most recent Kīlauea summit sulfur dioxide (SO2) emission rate was measured on October 22, 2022, at approximately 700 tonnes per day (t/d). USGS image by K. Mulliken.

An overflight, at approximately 10 a.m., on October 28, 2022, provided aerial views of the eruption within Halema‘uma‘u crater. Lava continues to erupt from the west vent area, supplying the lava pond in the western portion of Halema‘uma‘u. This video contains footage from two flights: one along the margin of Halema‘uma‘u crater, and one from farther away above Kīlauea caldera floor.

HVO volcanic gas specialists make sulfur dioxide (SO~2~) emission rate measurements downwind of the eruption within Halema‘uma‘u crater, Kīlauea summit. This video shows the typical fieldwork involved with measuring SO2 emission rates, during which HVO scientists drive traverses beneath the plume in the closed area of Hawai‘i Volcanoes National Park. As they drive, an ultraviolet spectrometer looks up at the plume to make the measurements. Access to the hazardous area is by permission from, and in coordination with, Hawai‘i Volcanoes National Park. Wind noise is audible in many clips.
