Clear weather today provided ideal conditions for HVO's observations of the water pond at the bottom of Halema‘uma‘u. Routine laser rangefinder measurements indicate that the pond continues to rise. The rate at which the water is rising is estimated to be less than one meter (yard) per week, so day to day changes in the pond dimensions are subtle. USGS photo by M. Patrick, 08-27-2019.
Telephoto view of the Halema‘uma‘u water pond today. Most of the water's surface is greenish-yellow in color. Steaming across the water rises slowly and moves with the shifting wind. Shimmering on the water, visible as tiny white specks in this image, appears on the pond surface intermittently. USGS photo by M. Patrick, 08-27-2019.
