Detailed Description

On June 8, 2021, the USGS Hawaiian Volcano Observatory conducted a routine helicopter overflight and fieldwork at the summit of Kīlauea. Here, a geophysicist returns to the helicopter after making Global Positioning Systems (GPS) measurements. These surveys measure small changes in the ground surface caused by subsurface magma movement. This scientist carries a GPS antenna along with a field backpack with essential gear, including food, water, and a field first aid kit. USGS photo by C. Parcheta.
