HVO geologists went to the summit of Kīlauea today to check for changes in the water at the bottom of Halema‘uma‘u and to look for a suitable site for a possible webcam installation. This wide-angle photo of Halema‘uma‘u shows just how difficult it is to see the water from the crater rim. USGS photo by C. Parcheta, 08/03/2019.

During their field work today, HVO geologists tested a new range finder to determine the distance to and size of the water ponds at the bottom of Halema‘uma‘u. Range finder measurements indicated that the water is about 663 m (2175 ft) below the tripod they had set up on the crater rim for observations. USGS photo by C. Parcheta, 08/03/2019.

With the help of a powerful telephoto lens, HVO geologists confirmed today that there are two areas of ponded water at the bottom of Halema‘uma‘u. Using a laser range finder from their observation site, they were able to measure the two greenish ponds. The main pond is about 11 m (36 ft) in diameter, and the smaller pond (above and slightly left of the main pond) is 6-7 m (about 20-23 ft) in diameter. USGS photo by C. Parcheta, 08/03/2019.

While making observations today, HVO geologists noted a koa‘e kea (white-tailed tropicbird) gliding across the ponded water at the bottom of Halema‘uma‘u. The bird is visible in the top left quarter of the photo. USGS photo by M. Patrick, 08/03/2019.
