Photo and Video Chronology – Kīlauea – August 5, 2022

Multimedia of recent activity on Kīlauea volcano.

Views of Kīlauea's continuing summit eruption

This timelapse sequence shows activity in Halema‘uma‘u, at the summit of Kīlauea, from March to August. The video shows the rise of the crater floor due to lava supplied beneath the surface crust, lifting the crater floor in an "endogenous" process. In addition, lava flows erupt sporadically and resurface portions of the crater floor.

The USGS Hawaiian Volcano Observatory KWcam at Kīlauea's summit has captured changes within Halemaʻumaʻu crater, at Kīlauea's summit since the eruption that began on September 29, 2021. The first image was taken on September 29, 2021, just before the eruption began; the second image was taken the morning of August 4, 2021, just after 9:30 a.m. HST and shows how much of Halemaʻumaʻu crater has filled over the past ten months. Since the eruption began, 98 million cubic meters (26 billion gallons) of lava has been erupted, which is about 40 times the The Great Pyramid of Giza in volume. This lava has filled 133 meters (437 feet) of the crater. Near-real-time images captured by the KWcam are available here: /volcanoes/kilauea/kwcam-live-panorama-halema-uma-u-.... USGS webcam images.

The USGS Hawaiian Volcano Observatory KWcam at Kīlauea's summit has captured changes within Halemaʻumaʻu crater, at Kīlauea's summit, due to the eruptions since December 2020.  The first image was taken on December 20, 2020, when there was still a water lake present within Halemaʻumaʻu; the second image was taken the morning of August 4, 2022, and shows how much of the crater has been filled within lava. Since returning to Halemaʻumaʻu in December 2020, lava has refilled about 17% of the volume of the 2018 collapse. Read more about the current eruption in this week's "Volcano Watch" article.

Recent Sentinel-1 interferogram for the period from June 7 to July 13, 2022 covering the Island of Hawai‘i. Each color fringe represents 2.83 centimeters (1.11 inches) of ground displacement. There is evidence for a few millimeters of inflation at Mauna Loa, and no noteworthy deformation at Kīlauea during this time span. In addition to ground deformation, this interferogram captures significant atmospheric noise. Copernicus Sentinel data was provided by the European Space Agency.

More photographs of the Airborne Electromagnetic and Magnetic (AEM) survey within Kīlauea caldera on July 28, 2022

During the survey, a helicopter flew about 150 feet above the ground, carrying a 40-foot diameter hoop suspended 35 feet below it. The system transmits weak, low-frequency radio waves into the ground, measures the Earth's response and passively detects variations in the Earth’s magnetic field. These variations will allow scientists to create an image of the shallow (upper 2,000 ft) magmatic structure, fault systems, and groundwater pathways beneath Kīlauea’s surface.
