Volcano Watch — Campaign season is here! Another way HVO tracks changes on Hawaiian volcanoes

Geodetic surveys measure the change in shape of our volcanoes due to changes in magma supply and storage. The USGS Hawaiian Volcano Observatory (HVO) has a long history of using many different types of instruments and technologies over the decades to detect these changes.
