Videos of the water lake at Kīlauea's summit

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. USGS video by M. Patrick.
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. No other unusual changes were observed in the lake. USGS video by M. Patrick.
