Detailed Description
HVO chief field engineer sets up a campaign GPS GNSS unit at station KEHU on Ka'upulehu crater as part of the ongoing Hualālai survey. During the survey, several GPS instruments are deployed at established benchmarks; their recorded positions can be compared with those from previous years to discern subtle patterns of ground deformation since the previous survey in 2015.
