Timelapse: 45 minutes of activity at Kīlauea's summit water lake

This timelapse video shows approximately 45 minutes of activity in the water lake at the summit of Kīlauea volcano. The video shows that the color zones are highly dynamic, shifting from minute to minute. This behavior has been common in the lake during much of the past year. Note that the camera exposure changes several times, shifting the color slightly at times. USGS

The colorful caldera lake at Kīlauea summit

The colorful caldera lake at Kīlauea summit. The view is from the western rim of Halema‘uma‘u crater, 1900 ft (580 m) above the water surface, in a restricted area of Hawai‘i Volcanoes National Park. USGS photo by M. Patrick 08/25/2020.

Timelapse showing typical activity at Kīlauea's summit water lake

This timelapse video at Kīlauea's summit covers approximately 30 minutes and shows the dynamic nature of the water lake in Halema‘uma‘u crater. Steam from the hot water surface is constantly shifting in the winds, while the migrating color boundaries on the water surface appear to show circulation in the lake. USGS video by M. Patrick.

Use of UASs (“Drones”) in 2018 at Kīlauea and Beyond

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. Angie is a member

Virtual flyover of Kīlauea summit

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.

Video of Kīlauea summit from May 29 overflight

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.

2018 Volcanic Threat Assessment helps prioritize risk efforts at U.S. volcanoes

Since 1980, there have been 120 eruptions and 52 episodes of notable volcanic unrest at 44 U.S. volcanoes.

Kīlauea volcanic ash sample
October 18, 2018

Sulfur dioxide (SO2)-rich emissions have long been a feature of Kīlauea Volcano's summit activity. However, vigorous volcanic ash production during the 2018 eruption raised new concerns about potential impacts for downwind communities.

On May 4, 2018, a powerful magnitude-6.9 earthquake on the south flank of Kīlauea Volcano shook the Island of Hawai‘i. It was the largest quake in Hawaii in 43 years. Today, more than five months later, smaller-magnitude earthquakes in the same area are still occurring.

The USGS Hawaiian Volcano Observatory (HVO) uses a diverse set of instruments to monitor active volcanoes in Hawaii. These include seismometers, gas sensors, Global Positioning System (GPS) stations, and webcams. Each provides a unique type of data critical to understanding volcanic systems.

The limited collapse of the inner part of Kīlauea Volcano's caldera this summer fell well short of the larger summit-wide collapses that occurred in the past. How many such limited collapses can we recognize at Kīlauea before written records were kept? The answer is none.

Kīlauea Volcano's 2018 lower East Rift Zone eruption and summit collapse provided a rare opportunity to study dynamic eruptive processes beneath and at the surface of the volcano.

In 1902, Thomas A. Jaggar, a geologist and founder of the Hawaiian Volcano Observatory (HVO), visited the scene of one of the most deadly volcanic disasters in modern history: Mount Pelee on the Caribbean Island of Martinique.

The USGS Hawaiian Volcano Observatory (HVO) has an extensive network of instruments that helps us monitor how the ground deforms due to magma moving underground. However, we are fortunate that scientific colleagues also pitched in to support our responses to Kīlauea Volcano's lower East Rift Zone (LERZ) eruption and summit collapse.
