Halema‘uma‘u water pond


image related to volcanoes. See description

Day-to-day changes in the water level at the bottom of Halema‘uma‘u are subtle and impossible to accurately measure. But when comparing views of the pond over several days some differences can be seen, as shown in these images. Rocks that were visible in the the water on September 2 could no longer be seen today (September 5). Note particularly that the two rocks protruding above water at the top of the September 2 photo are now submerged—evidence that the pond continues to slowly rise. USGS photos by D. Swanson.
