A telephoto image of the west vent in Halema‘uma‘u, taken from the northwest rim on November 3. Low roiling lava continues to erupt from the west vent, with occasional larger bursts of spatter. The spatter cone that has built up since the eruption began on September 29, contains ponded lava that supplies the lava lake through the tubed-over spillway.

A photo of the west vent and active western portion of the lava lake within Halema‘uma‘u, at Kīlauea summit. The eastern side of the lava lake (out of view to the right), has a stagnant solidified crust on the surface. USGS photo taken by L. DeSmither on November 3, 2021.

A telephoto image of the west vent in Halema‘uma‘u crater at the summit of Kīlauea. Ponded lava within the spatter cone supplies lava into the lava lake through the tubed-over spillway. The fast-moving lava stream is incandescent as it enters into the lava lake at the base of the cone.

The vent in the western wall of Halema‘uma‘u continues to erupt at the summit of Kīlauea. Volcanic gas emissions, primarily from the west vent (right), remain elevated. Sulfur dioxide (SO2) emission rates were measured at around 3,600 tonnes per day on October 28, 2021. USGS photo taken on November 3, 2021, by L. DeSmither.

A telephoto image of the northeast margin of the lava lake within Halema‘uma‘u, at Kīlauea summit, on November 1, 2021. The lava lake has now risen high enough to start covering the lowest portion of the down-dropped block on the north side of Halema‘uma‘u.

A wide view of the lava lake in Halema‘uma‘u, at the summit of Kīlauea, on November 1, 2021. This view, looking east, shows the west vent (bottom center) which continues to supply lava to the active portion of the lava lake, while the eastern portion (far side of lake) is crusted over.

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.

A sequence of telephoto images of the west vent (spanning 4 seconds), within Halema‘uma‘u at Kīlauea summit. The west vent continues to produce low-level lava fountains (seen here), which are forming an elevated pond of lava within the spatter cone.

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 granitic cliffs of Yosemite Valley produce frequent rockfalls, modifying the landscape but also posing risk to park visitors. Analyses of terrestrial lidar and historical structure-from-motion photogrammetry data provide relatively precise short-term (approximately 40 years) rates of rockfall and cliff retreat.

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. This view is from the south rim of the crater. 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.
