Color photograph of a crater at the summit of a volcano
HVO geologists made a routine visit to check on equipment at the summit of Kīlauea today, and had clear views across the floor of Halema‘uma‘u. The central portion of this photo is the region where much of the lava lake activity has occurred over the previous few years, with the area now showing only wispy plumes of weak gas emission. The summit region has been quiet in recent weeks, with low rates of seismicity and ground deformation. USGS photo by M. Patrick.

This photo shows the eastern portion of Halema‘uma‘u, at the summit of Kīlauea. The circular area of yellow coloration, near the top of the photo, is spot where the first lava fountain emerged in the September 2023 eruption. In the lower portion of the photo, the remains of Crater Rim Drive and the Halema‘uma‘u parking lot are visible. These paved areas were destroyed during the 2018 subsidence and collapse of the caldera floor. USGS photo by M. Patrick.
