The downhole seismological network in 1993 consisted of three accelerometers (4-component sensors) built by the CSMA and one hydrophone. The 4-component sondes were deployed in boreholes 4616 (https://cdgp.u-strasbg.fr/geonetwork/srv/fre/catalog.search#/metadata/SSF-4616), 4601 (https://cdgp.u-strasbg.fr/geonetwork/srv/fre/catalog.search#/metadata/SSF-4601) and 4550 (https://cdgp.u-strasbg.fr/geonetwork/srv/fre/catalog.search#/metadata/SSF-4550) ( at depths of around 1500m within the granite and were grouted in place. The hydrophone was deployed in EPS1 (https://cdgp.u-strasbg.fr/geonetwork/srv/fre/catalog.search#/metadata/SSF-EPS1) at a depth of around 2000m (Baria, R. 1996.The European HDR programme 1992-1995). The X,Y,Z coordinates in the file refer to the local coordinate system with the GPK1 wellhead as origin: X: Easting in meters from GPK1 wellhead (toward UTM32 East) Y: Northing in meters from GPK1 wellhead (toward UTM32 North) Z: Depth in meters from GPK1 wellhead The local coordinate system is based on the UTM32 system. The coordinates of the stations in the local coordinate system have been obtained from the report R 39025 of the BRGM by Hulot et al., 1996 (Testing the hodogram method on the 1993 Soultz microseismic data). The latitude, longitude and elevation in the WGS84 coordinate system have been derived from the local coordinate system. The associated catalogue is available (https://cdgp.u-strasbg.fr/geonetwork/srv/fre/catalog.search#/metadata/SSFS1993-catalogue).
