Compilation of recent photos of the water lake at Kīlauea's summit

This compilation of recent photos of the water lake at Kīlauea's summit shows the dynamic nature of colors and patterns on the water surface. The color boundaries can shift over minutes to tens of minutes. Greenish areas appear to be zones of hot water influx at the lake margins.

The light-colored boulder (see arrow on June 30 image) provides a reference point for the lake rise. On June 30 the boulder was well above the water surface. On August 25 it was at the shoreline. And on September 15 it was submerged. Laser rangefinder measurements indicate that the lake rose approximately 5 meters (16 feet) over this time span (June 30-September 15).
