This timelapse sequence shows 3.5 hours of activity at the water lake in Halema‘uma‘u crater, at the summit of Kīlauea Volcano. Several influx zones supply groundwater into the lake from the margins, creating shifting color zones on the lake surface. No significant changes have been observed in recent lake activity. USGS video by M. Patrick.

Just what is the Yellowstone Volcano Observatory? In this video, Mike Poland, Scientist-in-Charge of YVO, gives an overview of the institutions that make up the Observatory, how YVO monitors volcano and earthquake activity at Yellowstone, the geologic hazards of the region, and some of the noteworthy new results and observations from YVO scientists.

Yellowstone Volcano Observatory Scientist-in-Charge Mike Poland visits Yellowstone National Park to tell the story of how the ground there moves up and down over time. This motion has been measured using a variety of techniques over the past 100 years, and from geological mapping scientists can even tell how the ground has moved going back about 15,000 years!

A helicopter overflight on September 23, 2020, provided airborne views of the water lake at the summit of Kīlauea Volcano. Visual and thermal images collected during the overflight are used for mapping the slowly enlarging lake. A segment of the video shows the remains of Crater Rim Drive, a portion of which collapsed during the 2018 summit activity.

This video, taken on September 23, 2020, shows a small area of bubbling or upwelling along the western shoreline of the water lake at the summit of Kīlauea. This feature may result from a submerged fumarole (gas vent) on the crater wall. The extent of this feature is limited and it does not seem to have a significant effect on the overall lake surface activity.

This video shows a close-up of the northern shoreline of the water lake at the summit of Kīlauea Volcano. Steaming and subtle ripples are present on the water surface. Zooming out gives a sense of the scale of the lake. The lake level is approximately 576 meters (1890 ft) below the camera. USGS video by M. Patrick.

The color zones on the lake surface shift from minute to minute. This video shows how the color zones were creating a large swirl in the lake center. USGS video by M. Patrick.

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.

This time-lapse movie, which spans January 2019 to August 2020, shows the changing nature of the seasons at Yellowstone Lake as captured by the Yellowstone Volcano Observatory webcam. Snow and ice come and go, and there is even a wildfire visible during the summer of 2019!

Infrasound is an important tools for volcanologists, allowing them to detect eruptions, locate the source of explosions, and understand important parameters of volcanic events. John Lyons discusses how the technique is used by the USGS, especially in Alaska, and how we are working to help study infrasound around the world.
