A helicopter overflight on January 5, 2021, at approximately 8:30 a.m. HST allowed for aerial visual and thermal imagery to be collected of the eruption within Halema'uma'u crater at the summit of Kīlauea Volcano. The dimensions of the lava lake are 760 m (831 yd) E-W axis and 470 m (514 yd) in N-S axis.

View looking north across Kīlauea caldera from the south rim of Halema‘uma‘u, showing the ongoing eruption around 5:30 p.m. HST on January 5, 2021. The west vent activity included the “dome fountain,” effusive lava flows from a mid-elevation vent, and weak strombolian spattering activity from the high-elevation vent. USGS photo by K. Lynn.

Topography of Halema'uma'u crater, at the summit of Kīlauea Volcano, on December 26, 2020 (left), and January 5, 2021 (right). These Digital Elevation Models (DEMs) are created from aerial imagery collected during helicopter overflights. They show that the lava lake within Halema'uma'u continues to rise and deepen.

View through the laser rangefinder from the south rim of Halema‘uma‘u, Kīlauea Volcano summit, and showing the “dome fountain” and west vent effusive lava flow around 3:30 p.m. HST on January 5, 2021. A glowing vent is also visible at the top of the spatter structure. USGS photo by K. Lynn.

The activity at the Halema‘uma‘u west vent area on January 5, 2021, was dynamic. In the foreground, a “dome fountain” upwells from beneath the lake surface, pulsing with a bubble-like geometry. Just behind it, an effusive lava flow emerges from the base of the vent structure. A mid-elevation vent is also active, emitting another effusive lava flow.

The waves of sugar cane that once defined the Hawaiian island landscape of Maui, have slowly given way to non-native annual grasses in recent decades. Those grasses have become a fire hazard along the way.

The west vent in Halema‘uma‘u crater continues to erupt at Kīlauea’s summit. These telephoto images from December 29 (left) and December 30 (right) compare the lava lake surface below the west vent. The west vent is supplying lava to the lake through a crusted over channel, which was starting to form by December 30. USGS photos by H. Dietterich.

Lava forms a “dome fountain” at the inlet to the lava lake in Halema'uma'u crater January 2-3, 2021. Lava from the western vent cascades beneath roofed vertical channels to enter the lava lake at an inlet that has become partially submerged. The result is a rolling upwelling of lava near the inlet called a “dome fountain.”

Early this morning, the west vents in Halema‘uma‘u spattered from two places at the top of a small cone plastered on the northwest wall. This process can be seen in Kīlauea Volcano's summit F1 thermal webcam view of the lava lake.
