Continuous gravity data from K?lauea Volcano, Hawai?i

This Data Release contains continuous gravity records from two instruments on Kilauea Volcano, Hawaiʻ'i the HOVL gravimeter, located on the east rim of Halema'uma'u Crater directly above the 2008-2018 summit eruptive vent, and the PUOC gravimeter, located on northern rim of Puu Oo 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 Puu Oo. Although both gravimeters have data gaps of varying lengths owing to equipment outages, the data provided new insights into Kilauea's magmatic system that might not otherwise be known, including the density of lava within the summit and Puu Oo lava lakes and the occurrence of magmatic intrusions.
