This video taken on January 12, 2021, shows the west vent within Halema'uma'u crater at the summit of Kīlauea. Low fountaining of about 5 m (16 ft) high is visible inside the spatter cone that has formed. The fountain is producing a cascade of lava—about 35 m (115 ft)—down to the lava lake.
 

This video taken on January 11, 2021 shows the surface activity had increased at the western fissure over the past two days, within Halema'uma'u at the summit of Kīlauea. Low fountaining was supplying lava to an open channel that poured into the lava lake. 
 

This video shows crustal foundering and resurfacing at the lava lake in Halema‘uma‘u, at the summit of Kīlauea on January 8, 2021. Recently this foundering process has been common in the eastern portion of the lake. The video is shown at 20x speed.

This video shows activity at the western fissure, in Halema‘uma‘u at the summit of Kīlauea on January 8, 2021. The lava stream entering the lake appeared weaker than several days ago, when a dome fountain was active.
 

Visual photographs taken during a helicopter overflight of Halema'uma'u crater on January 7, 2021 (at Kīlauea Volcano) are used to create a 3D model of the crater. This technique is called structure-from-motion photogrammetry and uses the multiple perspectives captured in dozens of photos to reconstruct the crater shape on a computer.

A helicopter overflight at approximately 10:30 a.m. HST provided views of the ongoing eruption within Halema‘uma‘u crater. Video is shown at 3 x speed. HVO geologists noted that the dome fountain, which had been persistent near the base of the west vent area, had subsided and was no longer present. Lava continues to enter the lake at the base of the west vents.

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.

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.”

These videos show an increase in the surface activity where lava is entering the lake.

This is an animation showing the changing conditions of USGS streamgages from October 1, 2020 to December 31, 2020. The river conditions shown range from the driest condition seen at a gage (red open circles) to the wettest (blue closed circles). A purple outer ring around a gage indicates it is flooding.

This video, taken with a telephoto lens from an observation location on the rim, shows a process called “foundering”, in which a segment of cool lava crust on the surface of the lava lake is overridden by less-dense liquid from below causing the crust to sink into the underlying lake lava.

Video from a helicopter overflight of Kīlauea summit eruption on December 30, 2020, around 10:00 a.m., shows the western vents (area of bluish-colored gas emissions on left) erupting through crusted-over channels into a lava lake within Halema'uma'u crater.

This video, taken early morning on December 29, 2020, shows lava erupting from the west fissure in Halema‘uma‘u and pouring into the lava lake. Laser rangefinder measurements indicate that the opening lava pours from is 4-6 m (13-20 ft) wide. USGS video by H. Dietterich.
