GRT-2 is the second well drilled within the framework of the geothermal project ECOGI at Rittershoffen. The drilling of the well started in March 2014 and ended in July 2014. GRT-2 is a deviated well of 3196 m in length that reaches 2708 m TVD GL (true vertical depth from ground level) within the fractured granite basement. No reservoir enhancement was necessary at GRT-2. Production and circulation tests were realized from July to October 2014. The GRT-2 well is currently used as production well. It produces hot water at a temperature of 170 °C and with production flow rate of 70 L/s. Location of the GRT-2 wellhead (in WGS84): Latitude: 48.8970198° Longitude: 7.9386127°

Focal mechanisms of seismic events, which occurred during the thermal and hydraulic stimulations, the 2013 July burst and the GRT-2 drilling. Two earthquakes per seismogenic period were considered. More information about the determination of the focal mechanisms and the selection of events is available in the article from Maurer, V. et al., 2020, Seismicity induced during the development of the Rittershoffen geothermal field, France. The data parameters are the following: Column 1: Period Column 2: Date Column 3: Time (UTC) Column 4: Easting (m) Column 5: Northing (m) Column 6: Depth (m TVD MSL) Column 7: Latitude (°) * Column 8: Longitude (°) * Column 9: Mlv Column 10: NPOL Column 11: Dip (°) Column 12: Strike (°) Column 13: Rake (°) * The latitude and longitude in the WGS84 coordinate system have been derived from the extended Lambert II Cartesian system.

Seismological signals acquired during the development phase of the geothermal project at Rittershoffen. Waveforms from the permanent stations described in RITD-Surface_network (https://cdgp.u-strasbg.fr/geonetwork/srv/eng/catalog.search#/metadata/RITD-Surface_network) are provided for each event from RITD-Catalogue (https://cdgp.u-strasbg.fr/geonetwork/srv/eng/catalog.search#/metadata/RITD-Catalogue), (-30s, +90s). All the waveforms from the temporary seismic network installed in 2013 and 2014 are available on the GFZ (German Research Centre for Geosciences) data services website.

GRT-1 is the first well drilled within the framework of the geothermal project ECOGI at Rittershoffen. The drilling of the well began at the end of September 2012. The well reached a final measured depth of 2580 m within the fractured granite basement at the end of December 2012. Hydraulic tests of the well were carried out from December 2012 to June 2013. The tests realized at GRT-1 allowed to increase its injectivity index by a factor five. The GRT-1 well is currently used as injection well. Location of the GRT-1 wellhead (in WGS84): Latitude: 48.8970080° Longitude: 7.9387218°

Seismological signals acquired at Soultz-sous-Forêts during the 2000 Stimulation episode. The waveforms were recorded by a downhole and a surface seismological network during the hydraulic stimulation programme conducted at well GPK2 (https://cdgp.u-strasbg.fr/geonetwork/srv/eng/catalog.search#/metadata/SSF-GPK2). The downhole seismological network consisted of 5 stations and the surface network of 18 stations. The complete description of the downhole seismological network is available (https://cdgp.u-strasbg.fr/geonetwork/srv/eng/catalog.search#/metadata/SSFS2000-downhole_network). The complete description of the surface seismological network is available (https://cdgp.u-strasbg.fr/geonetwork/srv/eng/catalog.search#/metadata/SSFS2000-surface_network).

Before the 2003 episode, a permanent network designed to monitor the microseismic activity at Soultz-sous-Forêts was installed by EOST (Ecole et Observatoire des Sciences de la Terre) from the Strasbourg University. It consisted of nine stations, six one-component and three three-component sensors. The network was operational just before the 2003 stimulation of GPK3 (https://cdgp.u-strasbg.fr/geonetwork/srv/fre/catalog.search#/metadata/SSF-GPK3). A temporary network of fourteen seismometers (six three-component and eight one-component) was added to this permanent network. Contrary to the 2000 episode, all the fourteen stations of the temporary network were continuously recording. In addition to the network under the responsibility of EOST, a broad-band Güralp sensor was used mostly for waveform analysis. Two other accelerometers completed the surface monitoring system too. The coordinates of the stations have been obtained from RESIF (https://www.resif.fr/">https://www.resif.fr). Last update of data: 03/02/2020
