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.

A routine helicopter overflight of Kīlauea's East Rift Zone allowed Hawaiian Volcano Observatory geologists to conduct an updated visual and thermal survey. This video is shown at 2x speed and circles Pu‘u ‘Ō‘ō, the vent region for the East Rift Zone eruption between 1983 and 2018. No major changes were observed in Pu‘u ‘Ō‘ō.

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.

ANIMATED GIF: This animated image file (GIF) includes a series of thermal maps—ranging from daily to several weeks apart—made from helicopter overflight thermal imagery of Halema‘uma‘u crater, Kīlauea summit. The set of thermal maps are in a continuous loop showing the lava lake changes throughout the eruption.

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.

In this view of Kīlauea Volcano's south caldera area, the margin of the 1982 lava flows are visible (right), as is a portion of Crater Rim Drive. During World War II, bulldozers were used to create mounds in an effort to prevent planes from landing in this area of Kīlauea.

The fissure 8 lava flows of Kīlauea's 2018 lower East Rift Zone eruption meet the ocean at Pohoiki Bay, in the lower left corner of this image. Wave erosion of the 2018 lava flows along the coast contributes to sand accumulation that forms a beach at Pohoiki Bay. USGS image by K. Mulliken on March 4, 2021.

Steam was also visible in other portions of the 2018 eruption flow field, close to Kīlauea's East Rift Zone (bottom portion of image). As lava was flowing south towards the ocean in 2018, lava channels formed; these channels are visible as dark grey meandering lines in the image. Like water, lava flows along the path of least resistance downslope. USGS image by K.

Subtle steaming was visible at Pu‘u ‘Ō‘ō during HVO's overflight of Kīlauea on March 4, 2021. Steam is normally visible as the vent—which was active for more than 35 years—continues to cool, following the 2018 Pu‘u ‘Ō‘ō collapse.

HVO's overflight today also included KILAUEA's lower East Rift Zone, where geologists continue to document and map the 2018 eruption deposits. Fissure 8, visible in the center of this photo, emits steam as this geologically-young feature continues to cool.

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.

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.

During the overflight of Kīlauea's lower East Rift Zone on March 4, HVO scientists documented different lava textures in the fissure 8 flow field that formed during the 2018 lower East Rift Zone eruption. This photo shows an area of fissure 8 flows near the ocean. Both rubbly ‘a‘ā (brownish black) and smooth pāhoehoe (grey) are visible. USGS image by K.

An aerial view of Pu‘u Pua‘i, Kīlauea Iki, and Kīlauea caldera. Though the eruption within Halema‘uma‘u isn't visible from this vantage point, the bluish-tinged plume of volcanic gasses is visible near the center of the photo.

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.

View of the Kīlauea summit lava lake taken from the west rim of Halema‘uma‘u at 12:21 p.m. HST on March 3, 2021. The western portion of the lava lake is active with lava being fed from the west vent. The eastern surface of the lava lake remains crusted over. SO2 emission rates are elevated at approximately 1000 t/d, as measured on March 3, 2021.

This video explains how streamgages are used to measure the height and flow, or speed, of streams. By monitoring the height and flow of streams, the people who manage water infrastructure can have advanced noted of when the water is rising and how fast it’s coming.
