Water pond in Halema‘uma‘u continues to grow


image related to volcanoes. See description

Comparison of the water pond in Halema‘uma‘u on November 20, 2019, and March 1, 2020. Camera and lens same for both photos. Since November 20, 2019, the pond deepened 10 m (33 ft) and widened more than 50 m (164 ft) east-west and 30 m (98 ft) north-south. Circled clusters of rocks did not move between photos, evidence of slope stability. The water's color browned with time, though the photos probably exaggerate the color difference. The blue-green water at the far and near ends of the pond is interpreted as groundwater entering the pond. USGS photos by D. Swanson.
