This video describes USGS use of Unoccupied Aircraft Systems (UAS) or "drones" for use in 2018 at Kilauea Volcano in Hawaii. The speaker, Angie Diefenbach, is a leading expert in use of UAS for volcano surveillance and research. The presentation was given in June 2020 to colleagues in Ecuador who are interested in applications of UAS at their volcanoes.

A helicopter overflight provided aerial photographs of Kīlauea caldera on May 29, and these photos were used to construct a 3D model. The water lake is visible as the tan area in the deepest portion of Halema‘uma‘u crater. For scale, the water lake is 270 m (885 ft) long and approximately 600 m (1970 ft) below the western caldera rim. USGS photos by K. Mulliken.

This wide-angle video was captured during a helicopter overflight on May 29, and skirts the southern border of Halema‘uma‘u crater. The water lake, filling the bottom of the crater, was tan and brown today, and showed no significant changes. USGS video by M. Patrick.

A small rockslide occurred today on the south wall of Halema‘uma‘u, sending boulders into the water at the bottom of the crater. USGS video by M. Patrick.

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.

The 2018 Kīlauea eruption produced unprecedented levels of seismicity in the volcano’s instrumented history. The USGS Hawaiian Volcano Observatory documented about 80,000 earthquakes during the three-month-long eruption, starting with the dramatic collapse of the Puʻu ʻŌʻō cone on April 30 and ending with the final Kīlauea summit caldera collapse event on August 5.

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.

In the year since Kīlauea Volcano’s notable 2018 eruption ended, the lower East Rift Zone has been relatively quiet. But USGS Hawaiian Volcano Observatory scientists continue to gain insight into the eruption through ongoing research and monitoring. Some of the many questions asked by island residents include, Why did the fissures erupt along a linear pattern?

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.

The 2018 eruption on Kīlauea’s lower East Rift Zone spewed around a billion cubic yards of lava into Puna. From the moment the eruption began, samples of lava were collected and rapidly analyzed by a team of USGS Hawaiian Volcano Observatory and University of Hawaiʻi at Hilo scientists.

Kīlauea Volcano's summit has been in an eruptive pause since the 2018 events ended over a year ago. Nevertheless, it remains a dynamic place. Ongoing inflation and seismicity indicate that the summit magma chamber is gradually recharging.

Tens of thousands of earthquakes occur each year in Hawaii, making it one of the most seismically active places in the United States.

2018 and 2019 were years of profound change at Kīlauea Volcano and the USGS Hawaiian Volcano Observatory. Devastation caused by the largest lower East Rift Zone eruption and summit collapse in at least 200 years resulted in many transitions for island residents, including HVO.

This timelapse sequence shows two hours of activity at the water pond in Halema‘uma‘u, at Kīlauea's summit. Flow is evident along the sharp orange color boundary in the center of the pond, as well as along portions of the shoreline. The pond is 189 m (650 ft) long. The vido was taken on the eastern rim.

An overflight on December 18 provided aerial photographs of Kīlauea caldera, which were used to construct a 3D model. The water pond is visible in the deepest portion of Halema‘uma‘u crater. For scale, the water pond is 189 m (650 ft) long and approximately 600 m (1970 ft) below the western caldera rim.

USGS Hawaiian Volcano Observatory scientists Frank Younger and Patricia Nadeau talk about sampling the water at the bottom of Halemaʻumaʻu, a crater at the summit of Kīlauea Volcano. The water appeared in July 2019 and has steadily risen since then.

The Unoccupied Aircraft System (UAS) that collected water from the crater lake in Halema‘uma‘u on October 26 was outfitted with both visual and infrared (thermal) cameras. This reconnaissance video shows fumarolic activity on the walls of the crater. Fumaroles appear light in color (yellow and white) in the visual imagery due to alteration of the crater wall rock.

In this October 26 reconnaissance survey, the Unoccupied Aircraft System (UAS) reaches the northeast part of the Halema‘uma‘u crater lake, where large rocks at the lake margin are often used to visually track the rising water level. Taken over a period of about 5.5 minutes, the survey is shown at 3 times the speed it was filmed.

Prior to the Unoccupied Aircraft System (UAS) mission that collected a water sample from Halema‘uma‘u at Kīlauea's summit on October 26, reconnaissance UAS missions were flown. This video, taken over a period of 15 minutes, has been sped up 7 times to show the UAS as it approaches Halema‘uma‘u from the southwest.

This thermal video was captured by the UAS as it collected a water sample in Halema‘uma‘u, at Kīlauea's summit.
