Microseismic catalogue recorded by the EOPGS surface network and the downhole network at Soultz-sous-Forêts during the 1993 episode. The catalogue is part John Helm's thesis : The natural seismic hazard and induced seismicity of the European HDR (Hot Dry Rock) geothermal energy project at Soultz-sous-Forêts (Bas-Rhin, France), Appendix V. The events of the catalogue cover the 1st stimulation test, the 2nd packer test and the 2nd stimulation test of the 1993 episode.

Number of events: 96.

Time period: 07/09/1993 18:08:32 - 16/10/1993 19:56:43.

The data parameters used are the following:

Column 1: Seismic ID

Column 2: EOPGS event number

Column 3: CSMA file

Column 4: CSMA event number

Column 5: Date

Column 6: Corrected origin time (UTC)

Column 7: Easting from GPK1 wellhead *

Column 8: Northing from GPK1 wellhead *

Column 9: Depth from GPK1 wellhead *

Column 10: Latitude WGS84 **

Column 11: Longitude WGS84 **

Column 12: Elevation WGS84 **

Column 13: Event magnitude

Column 14: Seismic moment

Column 15: Source radius

* The local coordinate system is based on the UTM32 system.

** Latitude, longitude and elevation have been derived from easting, northing and depth from GPK1 wellhead.

The EOPGS microseismic surface network is available ( https://cdgp.u-strasbg.fr/geonetwork/srv/fre/catalog.search#/metadata/SSFS1993-surface_network ).

The microseismic downhole network is available ( https://cdgp.u-strasbg.fr/geonetwork/srv/fre/catalog.search#/metadata/SSFS1993-network ).

The velocity model used is available ( https://cdgp.u-strasbg.fr/geonetwork/srv/fre/catalog.search#/metadata/SSFS1993-velocity_model ).

Unfortunately the waveforms recorded by the surface network have been lost.
