  • Seismological signals acquired around Soultz-sous-Forêts during the 2010 circulation Episode. Waveforms from the permanent stations described in SSFC2010-Surface_network (https://cdgp.u-strasbg.fr/geonetwork/srv/eng/catalog.search#/metadata/SSFC2010-Surface_network) are provided for each event from SSFC2010-Catalogue (https://cdgp.u-strasbg.fr/geonetwork/srv/eng/catalog.search#/metadata/SSFC2010-Catalogue), (-30s, +90s).

  • Seismological signals acquired at Vendenheim during the development phase of the GEOVEN geothermal project. Waveforms from the permanent stations described in VDHD-Surface_network (https://cdgp.u-strasbg.fr/geonetwork/srv/fre/catalog.search#/metadata/VDHD-Surface_network) are provided for each event from VDHD-Catalogue (https://cdgp.u-strasbg.fr/geonetwork/srv/fre/catalog.search#/metadata/VDHD-Catalogue), (-30s, +90s). Data are automatically computed at request time

  • Surface seismic network used to study the Geoven Episode. The network consists of stations from several networks: Resif (https://www.resif.fr/) (FDSN code: FR), the French seismic network composed of high gain seismometers and accelerometers, French Accelerometric Network (FDSN code: RA), LRGB network (FDSN code: LE), the German network for Baden-Wuerttemberg, RaspberryShake network (FDSN code: AM) financed by the BCSF-Renass and the LabEx G-eau-thermie Profonde. Public stations from Fonroche network (ECK4 and VDH4) are included in the FR network. Data are automatically computed at request time

  • Geoven (http://www.geoven.fr) is a geothermal powerplant project led by Fonroche Géothermie now Arverne (https://arverne.earth/). The project is implemented on the site of the Rhenan Ecoparc at Vendenheim, north of Strasbourg. The geothermal powerplant produced 6 MW of electrical energy and 40 MW of thermal energy. To this end, two wells were used to draw the hot water and reinject it at more than 4000 meters deep. The two wells VDH-GT1 (https://cdgp.u-strasbg.fr/geonetwork/srv/eng/catalog.search#/metadata/VDH-GT1) and VDH-GT2 (https://cdgp.u-strasbg.fr/geonetwork/srv/eng/catalog.search#/metadata/VDH-GT2) had been drilled and some tests had been conducted (5 injectivity and productivity cycles between 02/2018 and 11/2019). A first interruption occured after a first period of seismicity (11/2019 – 01/2020, MLv=3.0 max) at Strasbourg and Vendenheim, to allow a third-party scientific expertise. During this period, the well was deepened of 450m to reach 5000m. New tests were authorized starting 10/2020, but were stopped on 28/10/2020 after a new period of seismicity with quake reaching 3.6MLv (04/12/2020). Authority decided on 07/12/2020 to definitely stop the project. Another earthquake of 3.9 ML (https://www.franceseisme.fr/donnees/intensites/2021/210626_0300/Rapport_BCSF-RENASS_2021R1_EVT210626-DPT67.pdf) occured on 26/06/2021. Authorities set up a committee of experts that delivered a first report (https://www.bas-rhin.gouv.fr/Politiques-publiques/Environnement/Geothermie/Rapport-du-comite-d-experts-cree-en-appui-a-l-administration-sur-la-boucle-geothermique-GEOVEN).
