Detailed Description
An HVO scientist takes gravity measurements at a benchmark near a crater in Hawaiʻi Volcanoes National Park. The gravimeter is the small, shoebox-sized instrument, which can measure a change in the force of gravity to one-in-one billionth of the force you feel every day. USGS photo by A. Ellis.
