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.
