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.

In places, the rock is incredibly dense and has to be slowly broken apart. This dense rock is interpreted by HVO geologists to be some of the last lava that erupted and solidified within the fissure 8 channel. USGS photo by C. Parcheta, 08-07-2019.

HVO geologists documented rock layers exposed in this road cut, noting the textures (density and vesicularity) and temperatures along a vertical line. USGS photo by C. Parcheta, 08-07-2019.

Using a thermal camera to measure the temperature of rock exposed in this road cut, HVO geologists determined that the void (just above the glove) in this pāhoehoe flow was 300 degrees Celsius (around 570 degrees Fahrenheit). USGS photo by C. Parcheta, 08-07-2019.

The water level at the bottom of Halema‘uma‘u continues to slowly rise, enlarging the area of the pond slightly over the past day.

Different portions of the ponds have different colors, presumably reflecting different amounts or varying chemistry of dissolved particles in the water.
