This close-up of the eastern end of the pond provides a better view of the varying surface color. Ripples are also obvious. USGS photo by M. Patrick, 08-30-2019.

These images look east at the pond within Halema‘uma‘u on August 8 and 14, 2019. The pond widened mainly toward the south (right). The north-south width of the pond on August 14 was about 32 m (105 ft), about 10 m (35 ft) wider than on August 8. The pond has widened and deepened slowly and steadily rate since measurements began on August 3.

HVO conducted an overflight of the lower East Rift Zone flow field to create a thermal map, which will be posted soon on the Maps page. This wide-angle photo shows the new path of Highway 132 through the Fissure 8 lava channels.

Two HVO geologists document road cutting activities on HWY 132 on August 7, 2019. One geologist is taking visual photographs while another geologist is taking thermal photographs to make a tandem pair for comparison. The temperature of the solidified lava was measured to 425° C (800° F) at the digging site.
