Detailed Description
During the annual Mauna Loa GPS campaign, 33 campaign stations are occupied with GPS instruments for days to weeks. The stations are spread across the flanks of the volcano and provide a synoptic picture of deformation on the volcano over the past year. The location of this survey was on the north flank of Mauna Loa, with clear views of Mauna Kea visible in the background. USGS photo by S. Conway.
