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.

Halema‘uma‘u crater lake on January 31
Field observations today show that the diameters of the crater lake within Halema‘uma‘u at the summit of Kīlauea are about 94 m (308 ft) north-south and around 192-195 m (630-640 ft) east-west. Too much steam at the west end interfered with measurements this morning.

Water samples collected from Halema‘uma‘u crater lake on January 17
On January 17, 2020, USGS-HVO scientists and DOI Unoccupied Aerial System (UAS) team members collected three additional samples of water from the Halema‘uma‘u crater lake. Here, the sampling device and temperature logger were readied for takeoff. The plastic sleeve was attached to the UAS (drone) with a cord about 20 feet (6 m) long.
