These data are microgravity measurements collected at the summit of Kilauea Volcano, Hawaii. Data are collected using multiple instruments, with each file representing measurements from a specific instrument during a specific time period. The data dictionary explains the file format and contents, and the dataset will be updated as new measurements are collected.

This Data Release contains continuous gravity records from two instruments on Kīlauea Volcano, Hawaiʻi: the HOVL gravimeter, located on the east rim of Halemaʻumaʻu Crater directly above the 2008-2018 summit eruptive vent, and the PUOC gravimeter, located on northern rim of Puʻu ʻŌʻō crater on Kīlauea’s East Rift Zone. Both instruments were collocated with GNSS stations. The HOVL gravimeter was installed in 2010 and operated until 2018, when it was destroyed by summit collapse. The PUOC gravimeter was installed in 2013 and operated until 2018, when it was removed following the cessation of eruptive activity at Puʻu ʻŌʻō. Although both gravimeters have data gaps of varying lengths owing to equipment outages, the...
These data are microgravity measurements collected in Yellowstone National Park. Data are collected using multiple instruments, which each data file representing measurements from a specific instrument during a specific time period.

Data Description Campaign microgravity surveys have been conducted at Kīlauea, Hawai‘i (USA), since 1975 (Dzurisin and others, 1980) and, when combined with deformation measurements, enable insights into mass change within the volcano (Jachens and Eaton, 1980; Johnson, 1992; Kauahikaua and Miklius, 2003; Johnson and others, 2010; Bagnardi and others, 2014; Poland and others 2019). For example, microgravity surveys between 1975-2008 measured residual gravity increases of up to 0.450 mGal across the volcano’s summit and have been interpreted as filling of void space by magma (Johnson and others, 2010). In March 2008 a new long-lived eruption began within Kīlauea’s Halema‘uma‘u crater (Wilson and others, 2008) which...
