Microseismic catalogue of the surface and the downhole network with magnitude from J. Helm - Soultz-sous-Forêts 1993 Stimulation

Description

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 here.
The microseismic downhole network is available here.
The velocity model used is available here.
Unfortunately the waveforms recorded by the surface network have been lost.
