RINEX files of GPS observations obtained in the Uturuncu volcano and surroundings (Altiplano-Puna Deformation Anomaly) during the November 2018 and November 2022 campaigns. In the 2018 and 2022 campaigns, 8 and 10 GPS stations have been installed respectively to help constrain the temporal deformation at Uturuncu volcano. The data contains the GNSS observations made in the 2018 campaign at the stations of Depeche Mode (DEMO), Foo Fighters (FOOF), Jimmy (JIMY), Led Zeppelin (LDZP), Metallica (MTLC), Sex Pistols (SEXP), UBQ4 and UTU Base (UBAS) In the 2022 campaign at the stations of Depeche Mode (DEMO), Foo Fighters (FOOF), IGGY, Jimmy (JIMY), Led Zeppelin (LDZP), Metallica (MTLC), Nirvana (NRVN), Offspring (OFSP), Sex Pistols (SEXP) and UTU Base (UBAS) The following devices were used to obtain these data: -Receiver Leica GR30 (serial numbers 1705008, 1705617 and 1705619) -Antenna Leica AS10 (serial numbers 16071044 and 16151018) -Integrate antenna + receiver Topcon Hiper Pro (serial numbers 326-1106 and 342-0370) -Masts "Nysiros style" and UNAVCO single pin + masts. The duration of data collection ranges from 1 day to 6 days depending on the site of the collection.

Reconstructed data - This dataset contains the reconstructed image data. Each sub-folder contains a set of 2D slices that together make up a 3D image from that time point. Not all images from all datasets have been reconstructed, the values in parentheses refer to the scan numbers that have been reconstructed. Raw data - This dataset contains the raw unprocessed image data collected during the development of the XRheo system. Processed data - This dataset contains the post-processing outputs from analysis of the data from the XRheo development experiments. Each sub-folder contains the files generated during filtering, segmentation and separation of the features [M (melt), B (bubbles), X (crystals)], and the post processing analysis for size distributions and tracking. The data sets included are the results of dynamic X-ray tomography experiments performed on multiphase synthesised magmas being deformed under known temperature and strain rates for a concentric cylinder geometry.

This data set contains a set of 20,740 unwrapped, geocoded interferograms derived from Sentinel-1 InSAR scenes processed over 63 volcanoes within the East African Rift system. A full description of the dataset is provided in the accompanying READMe file. This data set was first published in Albino, F. & Biggs, J. (2020).

Primary data, model initial conditions, model results, a compiled database of olivine diffusivity experiments and supplementary tables used in the paper: 'Mutch, E. J. F., Maclennan J., Shorttle, O., Edmonds, M. & Rudge, J. F., (2019), Rapid trans-crustal magma movement under Iceland, Nature Geoscience'. Data_S1 contains electron probe microanalysis (EPMA) profile data of olivine crystals used in this study. This file also includes all of the initial conditions for forsterite content (XFo), Ni and Mn used in the diffusion modelling. Standard deviations are averaged values of standard deviations from counting statistics and repeat measurements of secondary standards. Data_S2 is a compiled database of olivine diffusion experiments used to derive multiple linear regressions for diffusion coefficients and associated covariance matrices. Regressions were only made through [001] data. Data_S3 contains median values for all of the inverted parameters estimated for each crystal profile from the Nested Sampling Bayesian inversion for each type of initial condition and model equation. All of the Monte Carlo realisations for each model are also included in this file. Table_S1 is a supplementary table that contains olivine diffusion equation regression parameters derived and used as part of this study. Table_S2 is a supplementary table that contains covariance matrices for olivine diffusion equations derived in this study. Table_S3 is a supplementary table that contains covariance matrices for aSiO2 (silica activity) dependent olivine diffusion equations derived in this study. Table_S4 is a supplementary table that contains angles between the EPMA profile and the main crystallographic axes in olivine as measured by EBSD. These angles are incorporated into the anisotropy calculation used to determine the apparent diffusivity parallel to the measured profile. angle100P, angle010P and angle001P are the angles between the profile and [100], [010] and [001] respectively. Table_S5 is a supplementary table that contains ,median timescales and 1 sigma errors obtained from the posterior distributions of the Nested Sampling Bayesian inversion conducted on each olivine profile. The results using Al-based initial conditions, constant initial conditions (diffusion only), and aSiO2 based equations using Al-based initial conditions are presented here. The classification of each profile (growth-dominated vs. Al-decoupled) is also shown. See paper (Mutch, E. J. F., Maclennan J., Shorttle, O., Edmonds, M. & Rudge, J. F., (2019), Rapid trans-crustal magma movement under Iceland, Nature Geoscience) for more details.
