Data of the Hawaiian Volcano Observatory (HVO) Kīlauea Campaign Gravity Network (KCGN), 2009-2017

Published by U.S. Geological Survey | Department of the Interior | Metadata Last Checked: January 27, 2026 | Last Modified: 2022-08-12T00:00:00Z
In 2009, to increase the Hawaiian Volcano Observatory’s (HVO) microgravity monitoring capabilities, HVO acquired two Scintrex CG-5 Autograv gravity meters (serial numbers 90940579 and 90940578). Since 2009, these two relative gravimeters have been used to conduct campaign microgravity surveys at a network of 33 to 55 benchmarks across the summit region of Kīlauea Volcano, Hawai‘i (USA); the Kīlauea Campaign Gravity Network (KCGN). This data release comprises raw (as recorded by the gravimeters) and processed gravity data from campaign microgravity surveys of the KCGN between 2009-2017 using HVO’s Scintrex CG-5 relative gravimeters.
