A geologists makes observations at Kilauea
Clear weather allowed HVO geologists to make observations and take measurements of the water pond at Kīlauea's summit. No major changes were observed, and the water level continues to slowly rise. Note the former HVO observation tower can be seen above the geologist's helmet.

Changes in color at Kīlauea's summit water pond are common
This compilation shows the appearance of the water pond at Kīlauea's summit over the past two weeks. Day to day changes in the color of the pond are common, with portions of the pond shifting from a green hue to brown. A sharp color boundary has been common for several months in the same general area of the pond.
