Campaign GPS measurements on the Island of Hawaiʻi collected by the Hawaiian Volcano Observatory in 2021
This release includes data collected during campaign GPS surveys at Kīlauea and Mauna Loa Volcanoes on the Island of Hawaiʻi in 2021. It includes data from a total of 63 sites occupied from January 1 to December 31, 2021. For each site, we include its measured raw data in daily files, Receiver INdependent EXchange (RINEX) files for each day, field log sheet(s), and associated metadata...
Tiltmeter data from Kīlauea summit stations UWE and SDH from January 1 to December 31, 2020
Tiltmeter data from borehole tilt stations UWE and SDH from January 1 to December 31, 2020, spanning a Kīlauea summit intrusion and summit eruption that began on December 20, 2020. These data were collected in 2020 by Andria P Ellis and Ingrid A Johanson of the USGS Hawaiian Volcano Observatory. The authors thank Sarah Conway for conducting the nearly monthly clock resets for these...
Data of the Hawaiian Volcano Observatory (HVO) Kīlauea Campaign Gravity Network (KCGN)
Data Description Campaign microgravity surveys have been conducted at K?lauea, 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...
Campaign GPS measurements on the Island of Hawai`i collected by the Hawaiian Volcano Observatory in 2020
This dataset includes raw and rinex data from 2020 campaign gps data from the Island of Hawai`i in 2020. There was a total of 57 sites occupied. All data are included along with metadata, log sheets and raw/rinex data.

Rainfall an unlikely trigger of Kilauea’s 2018 rift eruption
If volcanic eruptions could be forecast from the occurrence of some external process, it might be possible to better mitigate risk and protect lives and livelihoods. Farquharson and Amelung1 suggested that the 2018 lower East Rift Zone (ERZ) eruption of Kīlauea Volcano—the most destructive eruption in Hawai‘i in at least 200 years2—was triggered by extreme precipitation, which caused...

A decade of geodetic change at Kīlauea’s summit—Observations, interpretations, and unanswered questions from studies of the 2008–2018 Halemaʻumaʻu eruption
On March 19, 2008, a small explosion heralded the onset of an extraordinary eruption at the summit of Kīlauea Volcano. The following 10 years provided unprecedented access to an actively circulating lava lake located within a region monitored by numerous geodetic tools, including Global Navigation Satellite System (GNSS), interferometric synthetic aperture radar (InSAR), tilt, and...

Insight into the May 2015 summit inflation event at Kīlauea Volcano, Hawai‘i
We use ground and space geodetic data to study surface deformation at Kīlauea Volcano from January to September 2015. This period includes an episode of heightened activity in April and May 2015 that culminated in a magmatic intrusion beneath the volcano's summit. The data set consists of Global Navigation Satellite System (GNSS), tilt, visual and seismic time series along with 25...

Monitoring network changes during the 2018 Kīlauea Volcano eruption
In the summer of 2018, Kīlauea Volcano underwent one of its most significant eruptions in the past few hundred years. The volcano’s summit and East Rift Zone magma system partially drained, resulting in a series of occasionally explosive partial caldera collapses, and widespread lava flows in the lower East Rift Zone. The Hawaiian Volcano Observatory (HVO) operates a robust permanent...

The cascading origin of the 2018 Kīlauea eruption and implications for future forecasting
The 2018 summit and flank eruption of Kīlauea Volcano was one of the largest volcanic events in Hawaiʻi in 200 years. Data suggest that a backup in the magma plumbing system at the long-lived Puʻu ʻŌʻō eruption site caused widespread pressurization in the volcano, driving magma into the lower flank. The eruption evolved, and its impact expanded, as a sequence of cascading events...

Very‐long‐period (VLP) seismic artifacts during the 2018 caldera collapse at Kīlauea, Hawaii
Throughout the 2018 eruption of Kīlauea volcano (Hawai‘i), episodic collapses of a portion of the volcano’s summit caldera produced repeated Mw 4.9–5.3 earthquakes. Each of these 62 events was characterized by a very‐long‐period (VLP) seismic signal (>40 s). Although collapses in the later stage of the eruption produced earthquakes with significant amplitude clipping on near‐summit...
