Over the past few months, HVO geophysicists have been conducting the annual high-precision Global Positioning System (GPS) survey of Kīlauea. The annual survey supplements HVO's continuous GPS monitoring stations and provides information on vertical and horizontal deformation of the ground surface.

HVO scientists continue their survey of Kīlauea caldera floor, including the down-dropped block, for diffuse volcanic gas emissions. This photo shows a large crack, on a portion of the caldera floor that subsided in 2018, that is emitting volcanic gas and steam.

Stacked lava flows are visible in the wall of the down-dropped block, which was exposed during the Kīlauea summit collapse events in 2018. A small exposure of lighter-colored volcanic ash, likely the Keanakāko‘i tephra deposits erupted during Kīlauea's last explosive phase several hundred years ago, is visible beneath tens of meters (yards) of lava flows.

Eruptive activity paused within Halema‘uma‘u, at Kīlauea's summit, a bit more than 2 months ago. In that time, the spatter cone at the western fissure complex has slowly degraded due to numerous small scale collapses, leaving a debris apron (fresh looking rubble) and exposing the interior of the spatter cone. USGS photo by N. Deligne.

A view looking north into Halema‘uma‘u on July 30, 2021. Although eruptive activity has paused at the summit of Kīlauea, HVO geologists still monitor the lava lake and summit area weekly. Lava lake surface depths remain the same since mid to late May when active lava was last observed at the surface. USGS photo by N. Deligne.

A USGS scientist calibrates two MultiGas instruments to prepare for mapping volcanic gasses on the floor of Kīlauea caldera. With the MultiGas strapped to metal backpack frames, the scientists traverse across the caldera floor to collect gas data which will be compared to the last survey.

While mapping volcanic gasses in Kīlauea caldera, HVO scientists got a view (looking west) of Halema‘uma‘u and the down-dropped block. The steep crater walls of Halema‘uma‘u are visible in the upper center and right portions of this photo, but the recently active lava lake is out of view below the eastern crater rim.

HVO geologists measure the depth to the water table at the Keller Well, located south of Halema‘uma‘u crater. The Keller Well is a borehole drilled in 1973 to a depth of 4,140 ft (1,262 m) that has been used to monitor the hydrology of the summit region of Kīlauea volcano.

The Yellowstone borehole geophysical network, installed by UNAVCO in 2007–2008. The placement of the boreholes is focused primarily around the caldera, and the boreholes contain a mix of instruments, including strainmeters, seismometers, tiltmeters, and pore pressure sensors.

This wide-angle aerial view looks southeast over Kīlauea's summit caldera, with the recently active lava lake in Halema‘uma‘u visible in the lower right. On the left side of the photo, the large cliffs formed during the 2018 collapses are visible. Kīlauea Iki can be seen in the upper left. USGS photo by M. Patrick, taken on July 22, 2021.
