Pu‘u ‘Ō‘ō remains quiet. Clear weather during HVO's August 22 overflight provided good views into the drained crater. Rubble from crater wall collapses has filled in much of the deeper part of the crater, with the bottom now at about 250 meters (820 feet) below the east rim. The curvature of the horizon is caused by the wide-angle view of the camera.

Clear weather afforded good views of the water pond in Halema‘uma‘u. No major changes were observed in the pond, but the water continues to slowly rise. The water surface was steaming, and its temperature was approximately 70 degrees Celsius (158 degrees Fahrenheit). For scale, the pond is about 70 meters (230 feet) long. USGS video by M. Patrick.

This video shows a close-up of the water pond at the bottom of Halema‘uma‘u on August 13, 2019. Steaming from the water surface shows the shifting winds over the pond.

This video shows a close-up of the ponded water at the bottom of Halema'uma'u. Yesterday, the separate ponds joined into a single elongate pond. The water level has continued to slowly rise.

This video shows steaming from the main pond of water at the bottom of Halema‘uma‘u as captured on Sunday, August 4. Two smaller areas of ponded water were present a short distance east of this spot. Thermal images indicate that the water surface is roughly 70 degrees Celsius (158 degrees Fahrenheit). USGS video by M. Patrick, 08-04-2019.

This video shows Moku‘āweoweo, the caldera at the summit of Mauna Loa, during a routine overflight. The flight path goes from northeast to southwest, and begins at North Pit crater before crossing over the main caldera floor. In the southwest portion of the caldera floor, the 1940 and 1949 cones can be seen.

This timelapse sequence of webcam images over a 24-hour period shows a typical day at the summit of Mauna Loa. The webcam (MLcam) is located on the northeast rim of Moku‘āweoweo, Mauna Loa's summit caldera. This sequence begins in the dark, with the moon rising (white dot at left in images), then brightens as the sun rises.

This wide-angle video shows the southwest portion of Kīlauea caldera in the area of Halema‘uma‘u. Faint plumes of volcanic gas are rising from yellow fumaroles on the walls of the deep conical pit. Overall, no significant changes were observed at the summit on today's overflight.

This 3D model of the Pu‘u ‘Ō‘ō crater was constructed from thermal images taken during a recent helicopter overflight. White areas show warm spots in the crater. Despite the absence of active lava in Pu‘u ‘Ō‘ō, changes at the crater have continued since magma drained from beneath it on April 30, 2018.

This video was taken during an overflight of the Pu‘u ‘Ō‘ō crater on Kīlauea Volcano's middle East Rift Zone. No major changes were observed, but the shape of the crater continues to be altered by continued rockfalls.

The 2018 Kīlauea Volcano eruption marked the first time the federal government used Unmanned Aircraft Systems (UAS) to assist in an eruption response in the United States.

This 3D model of Pu‘u ‘Ō‘ō's crater was created from thermal images during an overflight of the cone. The deepest portion of the crater is about 320 meters (1050 feet) below the crater floor that existed prior to April 30.
