Aerial view of Halema‘uma‘u at the summit of Kīlauea taken during a USGS Hawaiian Volcano Observatory helicopter overflight on August 1, 2019. The small green patch visible at the bottom of Halema‘uma‘u is a new pond forming at the lowest point of the crater. The pond is at about 525 m (about 1722 ft) elevation.

Zooming in even closer, an HVO scientist captured this image of the water on the floor of the crater during today's overflight. For more information, please read "Water or no water: that is (or was) the question"—HVO's Aug. 1, 2019, "Volcano Watch" article (https://volcanoes.usgs.gov/observatories/hvo/hvo_volcano_watch.html?vwid...).

The pond grew slightly in size and depth between the two dates; an "X" marks the same rock in both photos for comparison. Left photo courtesy of Ron Chapelle, Quantum Spatial.
