Over the past few months, HVO geophysicists have been conducting the annual high-precision GPS survey of Kilauea. The annual survey supplements HVO’s continuous GPS monitoring stations and provides information about vertical and horizontal deformation of the ground surface. These measurements inform HVO about Kilauea south flank movement as well as volume changes within subsurface magma reservoirs. Many of the survey locations are remote and accessible only via helicopter. This survey location was located on Kilauea’s East Rift Zone. USGS photo by A. Ellis.

Kilauea volcano is stirring once again, but scientists reassure that, for now, its volcanic activity is limited to the summit.
