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.

Data collected by 11 borehole tiltmeters operated by the U.S. Geological Survey on Kīlauea Volcano, on the Island of Hawai'i. Data was collected between 30 April, 2018 and 5 August, 2018. Among the features captured by this data set are: the collapse of Puʻuʻōʻō on 30 April, 2018, the migration of magma down the East Rift Zone from 30 April to 3 May, 2018, the M6.9 earthquake on 4 May, 2018, and the deflation and collapse of the shallow magma chamber at Kīlauea from early May until 5 August, 2018.

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, SMC, UWE) from January 1 to December 31, 2023. These data were collected in 2023 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 2018 lower East Rift Zone eruption of Kilauea Volcano began in the late afternoon of 3 May, with fissure 1 opening and erupting lava onto Mohala Street in the Leilani Estates subdivision, part of the lower Puna District of the Island of Hawai'i. For the first week of the eruption, relatively viscous lava flowed only within a kilometer (0.6 miles) of the fissures within Leilani Estates, before activity shifted downrift (east-northeast) and out of the subdivision during mid-May. Around 18 May, activity along the lower East Rift Zone intensified, and fluid lava erupting at higher effusion rates from the downrift fissures reached the ocean within two days. Near the end of May, this more vigorous activity shifted back uprift into Leilani Estates, where fissure 8 reactivated with lava fountains feeding several 'a'a flows. The southernmost flow lobe developed into a well-defined lava channel and reached the ocean at Kapoho Bay - 11 kilometers (7 miles) away - on 3 June. Fissure 8 continued supplying this lava channel for more than two months, constructing an approximately 3.5-square-kilometer (1.4-square-mile) lava delta along the coastline. Over 4 and 5 August, activity at fissure 8 waned and flow in the lava channel came to a halt, only to be followed by weak activity within the vent in late August and early September. By then, the eruption had covered 35.5 square kilometers (13.7 square miles) of the lower Puna District with lava. In this report, the authors have sought to chronicle this sequence of events using geospatial data in the form of an Esri file geodatabase, Esri shapefiles, and Google Earth KMZs.

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.
