September 17, 2024 — Annual Kīlauea GPS campaign underway

HVO scientists are conducting the annual Kīlauea GPS campaign. During the survey, GPS instruments are deployed at established benchmarks so that their recorded positions can be compared with those from previous years to discern subtle patterns of ground deformation associated with volcanic activity. Some of the GPS survey locations are drive-to, whereas others require helicopter support. USGS photo by A. Ellis.
