Microseismic catalogue of the downhole network recorded at Soultz-sous-Forêts during the 1996 episode. Calculated by the CSMA. Number of events: 3464.

The microseismic catalogue only covers the stimulation test and few days after. Almost no events were detected during the two lower flow rates of the stimulation. However, a large number of events were observed during the stimulation rate of 78 l/s.

Time period: 02:12:13 22/09/1996 to 17:30:45 28/09/1996.

The data parameters are the following:

Column 1: Seismic ID

Column 2: Event number

Column 3: Easting from GPK1 wellhead *

Column 4: Northing from GPK1 wellhead *

Column 5: Depth from GPK1 wellhead *

Column 6: Latitude WGS84 **

Column 7: Longitude WGS84 **

Column 8: Elevation WGS84 **

Column 9: Maximum peak to peak P-wave amplitude

Column 10: Maximum peak to peak S-wave amplitude

Column 11: Source radius

Column 12: Stress drop

Column 13: Moment magnitude

Column 14: Test name

Column 15: Date (yyyy-mm-dd)

Column 16: Time

* 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.
