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. Photograph by USGS geologist K. Mulliken.

Volcano Watch: Why is the 2018 lava still so hot?

As roads are recut into Kīlauea’s 2018 lava flow field, many have been surprised at how hot the lava remains under the surface, even though it is solidified.

This image is from a temporary monitoring camera on the west rim of Kilauea Caldera. The camera is looking E towards the bottom of the newly enlarged Halemaʻumaʻu crater. The crater from left to right (roughly NNE to SSW) is approximately 1 km (0.6 mi) across. The depth of the crater in the visible image from the rim is several hundred meters.

Day-to-day changes in the water level at the bottom of Halema‘uma‘u are subtle and impossible to accurately measure. But when comparing views of the pond over several days some differences can be seen, as shown in these images. Rocks that were visible in the water on September 2 could no longer be seen today (September 5). Note particularly that two rocks protruding above the water at the top of the September 2 photo are now submerged—evidence that the pond continues to slowly rise. USGS photos by D. Swanson.

Scientists use a laser diffraction particle size analyzer to examine fine ash from the 2018 Kīlauea summit explosions. The research examines fine ash (grains 1 mm to 1 micrometer) and investigates the processes of eruption, fragmentation, and respiratory health hazards (PM10, PM2.5). USGS image by A. Van Eaton

A small collapse of the Pu‘u ‘Ō‘ō crater at 6:14 a.m. HST today (May 1, 2019) was the last 'hurrah' for a GPS instrument located on the crater's edge (red circle). This station, designated PUOC, served faithfully throughout Kīlauea's 2018 eruption and was an important source of information on the shallow magma system of Pu‘u ‘Ō‘ō. The station's last reported position showed it moving rapidly to the southeast, consistent with motion into the crater (inset shows data transmissions from April 11 through this morning). Monitoring of Pu‘u ‘Ō‘ō is currently being accomplished by additional GPS and tilt stations farther from the edge of the crater. The larger equipment installation near the solar panels was not affected by this morning's collapse and continues to function. However, contingency plans are in place in case collapses of the crater edge continue. USGS photo by I. Johanson on March 18, 2019, annotated on May 1, 2019.

This image is from a temporary monitoring camera on the west rim of Kilauea Caldera. The camera is looking E towards the bottom of the newly enlarged Halemaʻumaʻu crater, although the deepest part of the crater is not visible from this vantage point. The crater from left to right (roughly NNE to SSW) is approximately 1 km (0.6 mi) across. The depth of the crater in the visible image from the rim is several hundred meters.
