Low fountaining remains active in the western fissure, supplying lava to the lava lake in Halema‘uma‘u crater, at the summit of Kīlauea. Spatter deposits have built up a spatter cone around the vent. Occasional collapses of the unstable cone rim drop large chunks into the vent, disrupting the fountaining and creating a more chaotic spray of lava around the cone. 
 

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.
 

A helicopter overflight on the morning of January 12, provided airborne views of the lava lake and active fissure within Halema‘uma‘u, at the summit of Kīlauea. Low fountaining was present at the western fissure, with active surface lava limited to the western portion of the lava lake. The eastern half of the lake was covered by cooler, solidified surface lava. 
 

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.
 

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. Visual and

Telephoto video of lava flow and fountaining in Halema‘uma‘u lava lake; spatter bursts from the active west fissure vent in Halema‘uma‘u.

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. Finally, the higher

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.”

Dome fountains have been observed during

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

Fissures Feed a Lava Lake at Halema'uma'u, at Kīlauea Volcano's Summit. Since fissures opened on December 20, 2020 in Halema'uma'u crater, USGS–Hawaiian Volcano Observatory scientists have maintained a 24-hour watch from the rim, taking measurements and making visual observations. This video captures fountaining activity at the two active vents during the early morning

Two fissure vents feed a growing lava lake at the bottom of Halema‘uma‘u crater. A preliminary calculation of volume suggests that since the start of the eruption on December 20, 2020, approximately 8-10 million cubic meters of lava have been erupted. This is equivalent to over 2 billion gallons, the volume of 3,000 Olympic-sized swimming pools.

 Telephoto videos capture fissure activity within Halema‘uma‘u crater on December 22, 2020, at approximately 3:35 PM HST. (1) The first video shows the main northern fissure.

During a helicopter overflight on December 21, 2020, at approximately 11:30 AM HST, Hawaiian Volcano Observatory scientists observed the northern fissure and lava cascade (right) supplying the majority of the lava into the lake, while the western (left) fissure was feeding several small channels that were

On December 20, 2020 just after 9:30 PM HST, lava began flowing from three fissure vents inside the crater of Kīlauea. The water lake at the base of the Halema'uma'u crater has boiled off. Lava is now feeding a growing lava lake. Additional photos and video are available at https://www.usgs.gov/

This timelapse sequence shows 3.5 hours of activity at the water lake in Halema‘uma‘u crater, at the summit of Kīlauea Volcano. Several influx zones supply groundwater into the lake from the margins, creating shifting color zones on the lake surface. No significant changes have been observed in recent lake activity. USGS video by M. Patrick.
 

This video, taken on September 23, 2020, shows a small area of bubbling or upwelling along the western shoreline of the water lake at the summit of Kīlauea. This feature may result from a submerged fumarole (gas vent) on the crater wall. The extent of this feature is limited and it does not seem to have a significant effect on the overall lake surface activity. No other

A helicopter overflight on September 23, 2020, provided airborne views of the water lake at the summit of Kīlauea Volcano. Visual and thermal images collected during the overflight are used for mapping the slowly enlarging lake.

This timelapse sequence shows the water pond in Halema‘uma‘u Crater, at Kīlauea's summit, between November 1, 2019, and March 26, 2020. Over this time the water level rose approximately 14 meters (46 feet), equivalent to 67 cm (about 2 feet) per week. The timelapse shows one image per day (with a few cloudy images removed), and is looped several times.

Stormy weather moved through the islands over the past day, producing snow at the higher elevations of Mauna Kea and Mauna Loa. This sequence shows the webcam images at the summit of Mauna Loa, and the variable weather throughout the day.

Tall and contiguous coastal dunes can substantially mitigate storm surge and flooding near our coasts. Understanding the position and height of dunes, as well as how these features change over time, is critical to the USGS mission of predicting impacts to coastal infrastructure and habitat caused by storms and hurricanes. To this end, the USGS operates a number of small

This thermal video of the fissure 8 cone shows that small areas of higher temperatures (greater than 100 degrees Celsius, or 212 degrees Fahrenheit) are present on the cone. Those hotter areas likely represent residual heat in the cone and the underlying fissure. USGS video by M. Patrick.

This video clip shows a flyover of fissure 8 on Jan. 21. During the 2018 eruption, lava spilled out from the cone into a channel that extended towards the north. Lava traveled approximately 13 km (8 miles) to reach the ocean at Kapoho Bay. USGS video by M. Patrick.

This timelapse sequence shows two hours of activity at the water pond in Halema‘uma‘u, at Kīlauea's summit.
