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

The microseismic monitoring at Rittershoffen began 6 months before any drilling. Four permanent stations were deployed at the surface in 2012 and completed the network of eight surface stations from the Soultz-sous-Forêts network. The permanent network is composed of one or three-components seismometers. A temporary network of 31 stations (TOPASE network) was deployed from June 2013 to November 2014 to improve the dectection and location of the seismic monitoring during the field development operations. The stations of the temporary network were three-component seismometers belonging to the Geophysical Instrument Pool Potsdam (GIPP) of the GFZ German Research Centre for Geosciences. Easting and northing in the file refer to the extended Lambert II Cartesian system. The latitude and longitude in the WGS84 coordinate system have been derived from the extended Lambert II Cartesian system.

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: 48.8965633979049 Longitude: 7.93818621036716
