The objective of the GeORG project (Geopotentials of the deep Upper Rhine Graben, https://www.geopotenziale.org/home/index_html) was to create a 3D model of the geological structure of the Upper Rhine Graben down to several kilometers depth. It provides a comprehensive information base (thickness/depth maps, temperature maps, and geological cross-sections that can be generated across the entire area). The BRGM distributes the French part of this 3D geological model via its Cupidon repository (https://data.geoscience.fr/metadataRecord/4a58a7e3-8b71-4c69-9447-cb1c791d23a3). We cut out this model around the Soultz-sous-Forêts site with a radius of approximately 10 km. Modeled lithological interfaces: 010_blg : Base of the Plio-Quaternary 040_bff : Base of the Froidefontaine Formation 050_bt :Base of the Tertiary 070_thr : Top of the Great Oolite 090_bju : Base of the Lias 100_bku : Base of the Keuper 110_tms : Top of the Saliferous Muschelkalk 120_bmu : Base of the Muschelkalk 130_btr : Base of the Triassic 170_kr :Top of the Hercynian 600_salt_diapirs : Salt diapirs faults_fr_s03: fault

The aim of the GeORG project (Geopotentials of the deep Upper Rhine Graben, https://www.geopotenziale.org/home/index_html) was to create a 3D model of the geological structure of the Upper Rhine Graben down to a depth of several kilometers. The project began in October 2008 and ended in December 2012. GeORG offers a complete geoscientific information base. Maps showing the deep structure and spatial distribution of geological layers and temperatures have been extracted. Geological cross-sections can be generated over the entire study area and in all directions. These show the stratigraphic position and stacking of layers in space. GeORG has created an information access platform for companies, public and private project developers and research organizations. The results are accessible to all at https://maps.geopotenziale.eu. Several products from the GeORG mapviewer around Vendenheim geothermal site are extracted.

GNSS data are recorded at REIC station at Vendenheim during VDHD Episode and are provided by the operator Fonroche. The data format is Rinex. The stations are described here (https://cdgp.u-strasbg.fr/geonetwork/srv/fre/catalog.search#/metadata/GNSS-Stations). See station location (https://cdgp.u-strasbg.fr/Obsnef-Gnss/situation.php) and data availability (https://cdgp.u-strasbg.fr/Obsnef-Gnss/teqc_heatmap.html?REIC).

Catalogue of microseismicity with magnitude recorded during the Geoven project at Vendenheim, calculated by the BCSF-Rénass (https://renass.unistra.fr/). The geographic extent of the catalogue is a square with sides of about 12 km approximately centered on the middle between the extremity of the two wells VDH-GT1 (https://cdgp.u-strasbg.fr/geonetwork/srv/fre/catalog.search#/metadata/VDH-GT1) and VDH-GT2 (https://cdgp.u-strasbg.fr/geonetwork/srv/fre/catalog.search#/metadata/VDH-GT2). Time period: 17/12/2016 - today. The data parameters are the following: Column 1: Seismic ID Column 2: Date and time (UTC) Column 3: Latitude Column 4: Longitude Column 5: Magnitude Column 6: Type of magnitude Column 7: Depth (km) Column 8: Type of depth Column 9: Catalogue Column 10: Evaluation mode Column 11: Number of stations used Column 12: Number of phases Column 13: Azimutal gap Column 14: Significant city Column 15: Distance of the city (km) Column 16: Type of event Remarks: The catalogue is automatically computed at request time. Not all the events of the requested catalogue are induced by geothermal activities. The induced events are referred as "induced or triggered event" in the column 16 of the catalogue.

This catalog was compiled by Minetto et al. (2025) and documents microseismic activity in the Vendenheim area from January 2018 to October 2023. The earthquakes in this catalog were detected with template matching, using recordings from the Strasbourg Dense Semi-permanent Seismic Network (DSSN) and the events located by BCSF-Renass (Bureau Central Sismologique Français – Réseau national de surveillance sismique). The earthquakes detected with template matching were relocated using a double-difference relocation method, and their magnitudes were estimated relative to those of the templates. Events that were successfully relocated are marked with "Yes" in Column 6. Events that could not be relocated are instead marked with "No" and were assigned the location of the template event that detected them. Minetto et al. (2025) identified eight main seismicity clusters using spatial clustering. The cluster ID of each event is reported in Column 7. Events that do not belong to any cluster have an empty field.
