Just a few days ago, Mauna Loa, the tallest active volcano on the planet, started erupting for the first time in 38 years.

An overflight on November 30, 2022, provided aerial views of the Northeast Rift Zone eruption of Mauna Loa. On the ground, Hawaiian Volcano Observatory scientists deploy a new webcam and measure fissure 3. USGS video by K. Mulliken. 

This video, taken during an early morning overflight on 30 November 2022, shows fissure 3, the dominant source of activity. The lava fountains are 20-25 meters in height (65-82 feet) and are feeding a lava flow that is moving to the northeast at ~130 meters per hour (0.08 miles per hour).

The eruption on the Northeast Rift Zone of Mauna Loa continues. This video shows the dominant fissure 3 remains active and is supplying lava to the flow advancing north. Taken on November 30, 2022.

Video showing fissures erupting on the Northeast Rift Zone of Mauna Loa the morning of November 29, 2022. Fountains at this area (fissure 3) were measured up to 25 m (82 ft) in height. 

An ‘a‘ā lava flow on the northeast flank of Mauna Loa. This lava flow is several meters thick and moving to the northeast. 'A'ā flows have a rough rubbly surface composed of broken lava blocks called clinkers. The clinkery surface covers a massive dense core, which is the most active part of the flow.

This video shows one of the fissures active on the Northeast Rift Zone of Mauna Loa. At approximately 11 a.m. on November 29, 2022, the fountains at this location were at measured 35-40 meters (115-148 ft) in height.

This video was taken by HVO field crews on the morning of November 29, 2022, and shows lava fountaining from a fissure vent high on Mauna Loa's northeast rift zone. Fissure heights of 20-25 meters (65-82 feet) were recorded at the time of the video.

The eruption on the Northeast Rift Zone of Mauna Loa Volcano continues. Today, the dominant fountain at fissure 3 was supplying lava to a flow advancing north of the rift zone.

November is Native American Heritage Month. Mike Poland, scientist-in-charge of the Yellowstone Volcano Observatory, talks about Indigenous peoples in the Yellowstone region and describes Yellowstone’s recent seismic, deformation, and geyser activity in this November 1, 2022 monthly update.

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.

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.

The update comes to you from Artist Paintpots in Yellowstone National Park. The paintpots are acid sulfate springs, one of three different types of thermal features in Yellowstone. 

Kīlauea volcano's summit eruption, within Hawai‘i Volcanoes National Park, began one year ago—on September 29, 2021. This three-minute video, produced by the Hawaiian Volcano Observatory, features footage from the past year and summarizes the eruption.

This timelapse sequence shows one image per day since March from the B1cam webcam on the east rim of Halema‘uma‘u, at the summit of Kīlauea. The images show that the floor of Halema‘uma‘u has been growing endogenously.

A routine helicopter overflight of the summit of Kīlauea provided airborne views of the lava within Halema‘uma‘u crater. The active lava lake is limited to the western portion of the crater floor, near the main source of white fume. The remainder of the crater floor consists of solidified lava flows.

Evening views of the eruption within Halema‘uma‘u crater on September 8, 2022. Solidified crust founders and sinks at the lava lake margin, and the lava lake sloshes. Lava spatters along the margin of the lake.

This timelapse sequence shows activity in Halema‘uma‘u, at the summit of Kīlauea, from March to August. The video shows the rise of the crater floor due to lava supplied beneath the surface crust, lifting the crater floor in an "endogenous" process. In addition, lava flows erupt sporadically and resurface portions of the crater floor.
