Whole rock analyses (presented in parts per million, ppm) of volcanic samples from Mt. St Helens, Washington, USA. Detailed sample descriptions and given in Blundy et al. (2008) and references therein. All samples were analysed using solution ICP-MS at the Open University. Blundy, J., Cashman, K.V. and Berlo, K. (2008) Evolving magma storage conditions beneath Mount St. Helens inferred from chemical variations in melt inclusions from the 1980-1986 and current (2004-2006) eruptions, in: Sherrod, D.R., Scott, W.E., Stauffer, P.H. (Eds.), A volcano rekindled: the renewed eruption of Mount St. Helens, 2004-2006, Reston, VA, pp. 755-790.

The data is provided as a single spreadsheet containing geochemical information from three volcanoes (Antuco, Chile; Jocotitlan, Mexico; Montserrat), all of which have been affected by major debris avalanches. The data was collected in order to investigate the long-term evolution of these volcanic systems. In addition, a single worksheet is provided of a summary database of published examples of volcanic debris avalanches. The geochemical data include bulk-rock XRF and ICP-MS data, Sr and Pb isotope measurements, and glass analyses for the Montserrat samples, along with site information for Antuco and Jocotitlan. Additional published analyses for Montserrat is availabile in published papers, as detailed in the spreadsheet.

Acoustic emissions (AE) and ultrasonic wave velocity data recorded during a series of high temperature thermal cracking experiments by Daoud et al., in the Rock and Ice Physics Laboratory of the University College London. The data gives the time and magnitude of AE output which were recorded contemporaneously whilst cyclically heating three rock types (A Slaufrudalur Granophyre, A Santorini Andesite and a Seljadalur Basalt). The ultrasonic wave velocity data was recorded pre- and post- heating. The data acquisition was permitted using a rock placed within an acoustic wave guide placed inside a high temperature furnace.

Microgravity data collected at Uturuncu Volcano located in the Altiplano-Puna Volcanic Complex, central Andes, in November 2022. Raw data collected along a survey line spanning from Laguna Colorada to Laguna Verde using a field gravimeter. All data have been preprocessed and corrected for tidal and drift effects. Data are reported with respect to reference station UBAS located to the west of Uturuncu near the Laguna Colorada.

Geochemical analysis of pyroclasts from Aluto, Ethiopia. Data are referenced in Clarke et al., 2019: Fluidal pyroclasts reveal the intensity of peralkaline rhyolite pumice cone eruptions; https://doi.org/10.1038/s41467-019-09947-8.

This dataset contains the locations and other pertinent information for 122 well-constrained seismic events that occurred on or near Corbetti between February 2016 and September 2017. These locations were derived from data collected on 37 broadband seismometers deployed as part of the RiftVolc project. The data were originally published in Lavayssière, A., et al. "Local seismicity near the actively deforming Corbetti volcano in the Main Ethiopian Rift." Journal of Volcanology and Geothermal Research (2019). https://doi.org/10.1016/j.jvolgeores.2019.06.008

See paper for full details. Data types: major element geochemistry; trace element geochemistry; 40Ar/39Ar geochronology. Table DR9 contains EPMA data of proximal lavas and ignimbrite fiamme. Table DR10 contains EPMA data of ash shards. Table DR11 contains EPMA standard data. Table DR12 contains LA-ICP-MS data of proximal lavas and ignimbrite fiamme. Table DR13 contains LA-ICP-MS data of ash shards. Table DR14 contains LA-ICP-MS standard data (raw). Table DR15 contains LA-ICP-MS standard data (corrected). Table DR16 contains 40Ar/39Ar geochronology data.

Laser ablation (LA) ICP-MS analyses (presented in parts per million, ppm) of melt inclusions from the 1980 eruption of Mt. St. Helens (18th May-16th October). Detailed sample collection methods are given in Blundy et al. (2008). Blundy, J., Cashman, K.V. and Berlo, K.

Surface level measurements of the Erebus volcano lava lake, Antarctica. Surface level was measured from a site at the crater rim using the Eredar radar system, a ground-based X-band FMCW radar (described in detail here: https://doi.org/10.1029/2018GL079177). The dataset contains a single continuous measurement period from 2016 (all times in UTC): 19 Dec 00:35 -> 19 Dec 19:21 Measurements were taken at a rate of ~0.25 Hz, using a 0.16 s 400 MHz bandwidth Linear Frequency Modulated chirp centred at 10.4 GHz, with 10 chirps being averaged for each measurement.
