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.

This reference map depicts the ongoing Kīlauea summit eruption on November 4, 2021. One eruptive vent is active within Halema‘uma‘u at this time, along the western edge of the rising lava lake.

The extent of the active surface of the lava lake (orange) within Halema‘uma‘u crater, at the summit of Kīlauea, is clearly delineated as the sun sets on November 2, 2021. Photo taken at 5:56 p.m. HST from the west rim. USGS photo by J.M. Chang.

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.

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.

Different views of an eruption from two predictable geysers. (a, c) Graphs showing water temperatures recorded by data loggers stationed near Beehive and Old Faithful Geysers, respectively. These data loggers were deployed by the Yellowstone Geology Program, configured to capture temperatures at one-minute intervals (indicated by blue dots).
