Tiltmeter data from Kīlauea stations (ESC, IKI, JKA, KAE, POC, SDH, UWD) from January 1 to June 30, 2025. These data were collected in 2025 by Andria P. Ellis of the USGS Hawaiian Volcano Observatory.

Tiltmeter data from Kīlauea stations (ESC, IKI, JKA, KAE, POC, SDH, UWD, UWE) from January 1 to December 31, 2024. These data were collected in 2024 by Andria P. Ellis of the USGS Hawaiian Volcano Observatory.

Tiltmeter data from station Jonika Flow (JKA) used in the publication "Pre-existing ground cracks as lava flow pathways at Kīlauea in 2014" by Tim R. Orr, Edward W. Llewellin, Kyle R. Anderson, and Matthew R. Patrick. These data were collected in 2014 by Asta Miklius of the USGS Hawaiian Volcano Observatory.

Tiltmeter data from Kīlauea stations (ESC, IKI, JKA, KAE, POC, SDH, SMC, UWE) from January 1 to December 31, 2022. These data were collected in 2022 by Andria P. Ellis of the USGS Hawaiian Volcano Observatory.

Tiltmeter data from Kīlauea stations (ESC, IKI, JKA, KAE, POC, SDH, SMC, UWE) from January 1 to December 31, 2022. These data were collected in 2022 by Andria P. Ellis of the USGS Hawaiian Volcano Observatory.

The dataset includes tiltmeter data at a sample rate of 1 sample per minute from a downhole tiltmeter at Uwekahuna Vault (UWE). Location is -155.291162, 19.420972 (NAD83), elevation 1257 m. Data has two orientations for each time sample (north and east). Each file contains a year of data. The original datasource removes the mean, so the ends of subsequent files will not align. The absolute value of tilt has little value, so the user should manually shift the records by a constant if alignment is required between year files.

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 21, 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 tiltmeters in 2020.

Following the 2018 collapses of the caldera floor at the summit of Kilauea Volcano (Anderson and others, 2019; Neal and others, 2019), the enlarged and deepened depression hosted a variety of volcanic activity between 2019 and 2022. These included an unprecedented water lake and two prolonged episodes of lava lake activity. This data release includes images from a stationary thermal camera poised on the western caldera rim, which provided a continuous record of the summit changes over this period. The thermal images provide an excellent observational record of the activity owing to the ability to see through thick volcanic fume, and the clarity with which they highlight active portions of the lava lake (Patrick and others, 2014). These thermal camera images cover three phases of activity at the summit of Kilauea. First, a water lake was present deep in Halema`uma`u crater from July 2019 to December 2020 (Nadeau and others, 2020). Second, a rising lava lake filled the bottom of Halema`uma`u from December 2020 to May 2021. Third, a second lava lake filled more of Halema`uma`u from September 2021 into early 2022 (through the end of this data release period in January 2022).
