March 4 overflight of Kīlauea summit and East Rift Zone

Another view of Kīlauea caldera, within Hawai‘i Volcanoes National Park. Ha‘akulamanu (Sulphur Banks) trail is visible in the foreground. The gas plume rising from Halema‘uma‘u in the background marks where the current eruption is taking place. Uēkahuna—the summit of Kīlauea—is visible in the upper right portion of the image.

Kīlauea Lower East Rift Zone Overflight—Lava Delta (March 4, 2021)

A routine helicopter overflight of the East Rift Zone of Kīlauea on March 4, 2021, allowed HVO geologists to conduct an updated visual and thermal survey. This video is shown at 5x speed and follows the new coastline created during the 2018 eruption in the Kapoho area. Lava along the shoreline continues to slowly erode, with small beaches forming in embayment's.

Lava Lake Depth March 4th

Data from a Kīlauea summit helicopter overflight on March 4th allowed for the calculation of the depth of the lava in Halema‘uma‘u crater. The deepest parts of the lake (darkest reds) exceed 200 meters (650 feet). Different-colored lines in Halema‘uma‘u show the perimeter of the lava lake and the vents over the course of the eruption. Rise of the lava lake has slowed in

Halema‘uma‘u eruption sequence Digital Elevation Models

HVO uses regular Kīlauea summit helicopter overflights of Halema‘uma‘u crater to create digital elevation models (DEMs) of the crater. The DEMs show changes in the crater over time and can be used to estimate erupted volume, eruption rate, and map features of interest. In this sequence of DEMs, the rise of the lava lake can be clearly tracked as well as the movement of the

Fly-Through of Halema‘uma‘u Crater Model (March 4, 2021)

Visual photographs taken during helicopter overflights of Halema‘uma‘u Crater are used to create 3D models 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. HVO scientists use these models to help calculate erupted volume, eruption rate, and measure

The lava lake in Halema‘uma‘u crater remains active. This view looking to the northwest on Wednesday, March 4, 2021, focuses on the active portion of the lake; the eastern stagnant portion is out of view to the right. Lava enters the lake at the base of the western vent spatter cone (left). This photo was taken in an area of Hawai‘i Volcanoes National Park that remains

March 4 overflight of Kīlauea summit and East Rift Zone

HVO scientists conducted an overflight of Kīlauea's summit the morning of March 4 to document the ongoing eruption. No significant changes were observed—the vent in the northwest wall of Halema‘uma‘u continues to erupt and lava continues to slowly fill the crater. Laser rangefinder measurements from the morning of March 4 indicate that lava has filled about 220 meters (772

Wide-angle view of Pu‘u ‘Ō‘ō, March 4, 2021

During a routine overflight of the Kīlauea East Rift Zone on March 4, HVO scientists visited the Pu‘u ‘Ō‘ō area to check for any significant changes in recent months. Their most notable observation was further accumulation of talus—rock collapse debris—in the crater that formed on April 30, 2018, as seen in this wide-angle photo. This talus pile now almost completely fills
