This close up shows the water in the western end of the lake. Greenish water zones tend to be hotter, and appear to be zones of groundwater influx into the lake. Submerged rocks are visible along the shoreline, and appear to have a brown or orange color. USGS photo 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. USGS video by M. Patrick.
