A view into the center of Pu‘u ‘Ō‘ō. Collapses on the crater walls have enlarged sections of the crater and filled the bottom of the crater with rockfall debris. The deepest portion of the crater is about 286 m (938 ft) below the crater floor that existed prior to the collapse on April 30, 2018. Steam rises from the loose rock on the crater floor.

On May 7, 2019, field crews visited a telemetry hub on the rim of Pu‘u ‘Ō‘ō to assess damage after a small collapse on May 1. During the overflight, photos and observations were made of the Pu‘u ‘Ō‘ō crater. The crater walls expose a clear sequence of lava flows and cinder that built the cone in the early 1980s.

This lava fountain, which erupted on September 6, 1969, during the Mauna Ulu eruption, was about 540 m (1770 ft) tall. The tephra cone, eventually named Mauna Ulu, can be seen in the fallout area (right of the fountains. in middle of image). It is now a 121 m (397 ft) tall lava shield in Hawai‘i Volcanoes National Park.

Teaching Through Technology (T3) Alliance students in the University of Hawai‘i at Hilo Upward Bound summer program install a large display showing measurements from their air-quality monitoring station outside the Pāhoa Community Center, which was used as a temporary shelter for displaced residents from Kīlauea Volcano's 2018 eruption.

Good weather provided clear views of Halema‘uma‘u during a routine visit to the webcam on the northwest rim of the caldera.
