Composition of Soil-Gas Efflux From the Artu Jawe Fault Zone, near Aluto volcano, Ethiopia (NERC grant NE/L013932/1)
Composition of Soil-Gas Efflux From the Artu Jawe Fault Zone, near Aluto volcano, Ethiopia. Data are referenced in Hutchison et al., 2016a: Causes of unrest at silicic calderas in the East African Rift: New constraints from InSAR and soil-gas chemistry at Aluto volcano, Ethiopia; https://doi.org/10.1002/2016GC006395.
A geographic information system (GIS) heat flow and temperature model of East Africa created by extracting data from open sources into a series of shapefiles and rasters containing information on geothermal sites, hot spring locations, digital elevation model, surface temperature, geothermal gradients, thermal conductivities and heat flow data, major faults, surface geology, crustal basement, electrification grid system and population density across East Africa. This data is stored in the World Geodetic System (WGS) 1984 Geographic Projection System.
Diffuse CO2 degassing data from three campaigns across the Main Ethiopian Rift (NERC grant NE/L013932/1)
Diffuse CO2 degassing data from three campaigns across the Main Ethiopian Rift. Data are referenced in Hunt et al., 2017: Spatially variable CO2 degassing in the Main Ethiopian Rift: Implications for magma storage, volatile transport and rift-related emissions; https://doi.org/10.1002/2017GC006975.
This data set comprises broadband magnetotelluric (MT) and transient electromagnetic (TEM) data collected during three field seasons in 2008, 2009 and 2010 by a team of researchers from the University of Edinburgh, UK, IMAGIR, Brest, France and the Institute for Geophysics, Space Science and Astronomy at Addis Ababa University, Ethiopia. The MT dataset includes the original time series and processed transfer functions. The time series data are provided in the original raw data format with files to convert them to ascii. Raw and processed TEM data, collected with a Geonics PROTEM system, are included. We provide information on the locations and the processing and include the necessary instrument response functions and metadata to reproduce our results from the raw data.
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).
