These processed data and provisional codes were created to investigate seismic velocity changes associated with the collapse of Kīlauea caldera during its 2018 eruption. Primary data (i.e., seismic waveforms) are hosted at the Incorporated Research Institutions for Seismology (IRIS; https://www.iris.edu/) and are ingested by the codes included here to reproduce the data analyzed in Hotovec-Ellis et al., 'Earthquake-derived seismic velocity changes during the 2018 caldera collapse of Kīlauea volcano.' The included code ('cwire' short for Coda Wave Interferometry with Repeating Earthquakes) takes a catalog of earthquakes clustered by waveform similarity (e.g., REDPy, https://github.com/ahotovec/REDPy/) and processes...

The youngest and largest island in the State of Hawaii—the Island of Hawai‘i—is formed by five volcanoes, three of which have erupted within recent geologic history: Mauna Loa, Kīlauea, and Hualālai. This data release provides a chronology for activity and impacts at Mauna Loa, Kīlauea, and Hualālai over approximately the past two and a half centuries. This data release includes a word document, “HI_volcanoes_chronology_description,” that describes the data compilation process and provides simple summary tables of eruptive activity and maps. A CSV file contains the compiled eruption chronology data for all volcanoes—"HI_volcanoes_chronology_data”—references for which are provided in a separate CSV file titled “HI_volcanoes_chronology_references.”...
This data release provides volcanic plume heights from the summit of Kīlauea Volcano for 2008-2015, and during the eruptive events of 2018. For 2018, a Secacam Wild Vision Full HD camera with a 7mm focal length was located at 1717 m elevation approximately 15 m south of the Mauna Loa Strip Road within Hawaiʻi Volcanoes National Park, 19.475843°N, 155.363560°W (WGS84). The camera was pointed southeast to capture images of the Kīlauea caldera every two minutes. These images were used to calculate maximum plume heights within the full frame of the camera. For each two-minute image, the maximum plume heights above the Halemaʻumaʻu crater rim, and in the overall image, were calculated using the horizontal distance to...

Kīlauea Volcano on the Island of Hawai‘i was in a state of nearly continuous eruption from 1983 – 2018. Large amounts of sulfur dioxide gas (SO2) were released from the volcano’s East Rift Zone (ERZ) during the entire eruptive period, and from the Overlook vent at the summit of the volcano from 2008-2018. This data release presents ground-based estimates of SO2 emission rates from the two gas emission sources for the period 2008-2013. For the two-year period 2008-2010, the summit data have been revised from previously published emission rates (Elias and Sutton, 2012). During this era, very high emissions from the volcano’s newly active lava lake led to opaque plumes and challenges in accurately quantifying SO2 column...
