Eruptive activity resumed today in Halema‘uma‘u crater, at the summit of Kīlauea volcano, after a brief pause of several days. This video shows spattering and lava effusion from the west vent, which has built a steep spatter cone. 

Structure-from-motion techniques use photographs taken from different angles to reconstruct the three-dimensional shape of an object. At Kīlauea, this technique has been used to rapidly generate maps of eruption activity from aerial imagery, allowing scientists to quantify changes over time such as the volume of lava erupted and surface area covered by lava.

Eruptive activity on the west side of HALMEMAUMAU crater, Kīlauea summit, on December 20. Audible bubble bursts from the west vent (lower right) produced brown-tinted gas plumes with entrained lava fragments. The bursts also created pressure waves that displaced the white steam.

Olivine—the green mineral found in Hawaiian lavas—and its chemistry can tell us a lot about how, when, and where magmas move inside volcanoes before they erupt. Join Hawaiian Volcano Observatory geologist Kendra J.

Lava continues to erupt from a perched lava pond within the west vent of Halema‘uma‘u crater at the summit of Kīlauea. This video shows nearly continuous spatter bursts through the pond and a roiling and sloshing pond surface. At about 43 seconds into the video, a white-trailed tropicbird (koa‘e kea) flies through the frame.

Lava continues to erupt from the west vent in Halema‘uma‘u, and supply the lava lake through a spillway in the spatter cone. On November 12, a small overflow of the perched lava lake levee was visible from the western crater rim. Overflows are an important process for building up perched levees, as they help add height and stability.

Lava continues to erupt from the west vent in Halema‘uma‘u, and supply the lava lake through a spillway in the spatter cone. On November 9, a close-up view of the west vent shows spatter bursting and sloshing within the cone. Spatter was thrown about 6–9 m (20–30 ft) above the pond surface, occasionally depositing spatter onto the rim of the cone. 

Eruptive activity continues in Halema‘uma‘u, at the summit of Kīlauea. The west vent remains active with low fountaining in a slightly perched pond set within the cone. Lava pours through a short spillway into the lava lake. The base level of the pond fluctuates over the timespan of minutes.

It has been one month since the new eruption began in Halema'uma'u. Over the past year at Kīlauea summit there has been a water lake and two eruptions within Halema'uma'u crater.

The volcanic activity of Kilauea continues on the island of Hawaii. The latest eruption began within Halema'uma'u Crater on September 29. The previous eruption just ended in May 2021. Before that, major lava flows covered the eastern tip of Hawaii's Big Island in 2018. This latest eruption included vigorous fountaining up to 50-60m high.

Morning views of the eruption within Halema‘uma‘u crater, at Kīlauea summit, on October 23, 2021. Variable west vent fountain heights are visible in this video, which is shown at 5 times speed.

Lava continues to erupt from a single vent on the western wall of the crater. Lava fountains within the cone and spills out of the cone opening, flowing east into the lake.

A morning overflight of Kīlauea summit on October 15, 2021, provided aerial views of the eruption within Halema‘uma‘u. Lava erupts from a single vent on the western wall of the crater. The vent has a spatter cone around it, with an opening to the east from which lava flows into the lava lake. 

Lava continues to erupt from the western vent in Halema‘uma‘u. On October 12, a short-lived vent (erupting for approximately 10 hours) was present to the north of the main vent (right). Lava fountaining from the main vent was 10–15 meters (30–50 ft) above the lake surface, with larger bursts exceeding the height of the cone (30 meters or 100 ft).

The eruption continues within Halema‘uma‘u crater, at the summit of Kīlauea. The western vent supplies lava into the lava lake through a short spillway. Consistent fountain heights of 10–15 meters (30–50 ft) were interrupted by frequent larger busts of spatter exceeding the height of the cone (30 m or 100 ft). 

Eruptive activity continues at the west vent in Halema‘uma‘u crater, at the summit of Kīlauea. When this video was taken on October 12, a small subordinate vent was present on the north side of the main fountaining vent. The main fountaining source was supplying lava into the lake via a short spillway.

Kīlauea summit eruption lava fountain height in Halema‘uma‘u crater on October 10, 2021 was highly variable. A persistent low fountain a few meters (yards) tall was frequently interrupted by larger series of bursts throwing lava more than 15 meters (50 feet) into the air and onto the interior walls of the vent cone.

The eruption continues in Halema‘uma‘u crater, at the summit of Kīlauea. Lava fountaining no longer emerges from the central portion of the lake, with fountaining limited to the west vent shown here. Low fountaining within the cone supplies lava into the lake via a short spillway.
