Excellent overview of lava lake, back wall and crater floor of Halema’uma’u. Shot from crater rim at Halema’uma’u overlook.
USGS: “This video shows an overview of the lake from the Halema‘uma‘u Crater rim, as well as some of the spattering that was occurring on the lake margin on Sunday, April 22.”
Apirl 25: USGS Handheld Video of Lava Lake
You can see how much it overflowed in just 3 days. Taken from crater rim, Halema’uma’u overlook.
USGS: “On Kīlauea Volcano’s summit, the Halema‘uma‘u lava lake’s high standing lake level produced intermittent overflows onto the crater floor. Smaller overflows and spattering have started to build a few discontinuous levees and a spatter cone around the lake margin, shown in these video clips taken from the lakes north and northeastern margin.“
April 26: USGS Helicopter Overflight
USGS: “Vigorous overflows from Kīlauea’s summit lava lake covered a large portion of the floor of Halema‘uma‘u this morning. In this video, the view starts from the north and heads south, showing the north and east sides of Halema‘uma‘u crater. During the overflight, a large overflow was active on the north margin of the lava lake, sending a cascade of lava down the elevated lake rim.”
April 25-27 Timelapse From HVO Webcam
USGS: “This time-lapse video from 7:30 p.m. April 25 to 7:30 p.m. April 26 shows Halema‘uma‘u lava lake producing intermittent overflows onto the crater floor. The largest of these flows was from approximately 6:15 a.m. to 10:30 a.m. on April 26 and covered about 90 acres (2/3) of the crater floor.”
Excellent retrospective the USGS put out in 2017 on the then nine-year-old lava lake at Kilauea’s summit, with great information and spectacular views:
USGS video description:
In March 2008, a new volcanic vent opened within Halema‘uma‘u, a crater at the summit of Kīlauea Volcano in Hawaiʻi Volcanoes National Park on the Island of Hawaiʻi. This new vent is one of two ongoing eruptions on the volcano. The other is on Kīlauea’s East Rift Zone, where vents have been erupting nearly nonstop since 1983. The duration of these simultaneous summit and rift zone eruptions on Kīlauea is unmatched in at least 200 years.
Since 2008, Kīlauea’s summit eruption has consisted of continuous degassing, occasional explosive events, and an active, circulating lava lake. Because of ongoing volcanic hazards associated with the summit vent, including the emission of high levels of sulfur dioxide gas and fragments of hot lava and rock explosively hurled onto the crater rim, the area around Halemaʻumaʻu remains closed to the public as of 2017.
Through historical photos of past Halemaʻumaʻu eruptions and stunning 4K imagery of the current eruption, this 24-minute program tells the story of Kīlauea Volcano’s summit lava lake—now one of the two largest lava lakes in the world. It begins with a Hawaiian chant that expresses traditional observations of a bubbling lava lake and reflects the connections between science and culture that continue on Kīlauea today.
The video briefly recounts the eruptive history of Halemaʻumaʻu and describes the formation and continued growth of the current summit vent and lava lake. It features USGS Hawaiian Volcano Observatory scientists sharing their insights on the summit eruption—how they monitor the lava lake, how and why the lake level rises and falls, why explosive events occur, the connection between Kīlauea’s ongoing summit and East Rift Zone eruptions, and the impacts of the summit eruption on the Island of Hawaiʻi and beyond.
