Geodesy:
InSAR:
- Corbetti InSAR dataset contains a set of 226 unwrapped, geocoded interferograms derived from InSAR scenes processed over Corbetti Volcano, Ethiopia. The data were assembled from multiple sensors (ALOS, ENVISAT, CSK and Sentinel) and processed using either the ICSE or GAMMA software package. The images presented here are generally not the same size as the raw InSAR images but instead are cropped to the extents of the volcano and its immediate environs. This dataset is deposited in the NGDC under ID: 125198
- This data set contains 119 unwrapped and geocoded interferograms derived from Cosmo-SkyMed (CSK) SAR scenes acquired over Fentale Volcano in the Northern Main Ethiopian Rift between June 2014 and December 2015. This data set also contains displacement time series derived from processed CSK and Sentinel-1 interferograms at the locations specified in the accompanying README file. This data is deposited in the NGDC under ID: 131186. Data DOI: https://dx.doi.org/10.5285/650ca965-8ad5-4f44-a560-e0dc3decd642
- This dataset contains 204 ascending and 300 descending Sentinel-1 geocoded unwrapped interferograms and coherence, and 70 ascending and 102 descending Re-sampled Single Look Complex (RSLC) images for each acquisition date. This data set also includes the original size Digital Elevation Model (DEM) used during InSAR processing.

Seismology: Raw seismic waveforms and station metadata for 2016-2017 deposited with IRIS with restricted access. Data set can be searched for by using a defining search box on the map found on this page http://ds.iris.edu/ds/nodes/dmc/forms/breqfast-request/ (network code Y6). Access to the actual data may need to be coordinated through SEIS UK/Derek Keir (?) if data set is still under the embargo.
Seismic catalogue for Corbetti Volcano, Ethiopia: 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 ID: 130005
