Microseismic catalogue with moment magnitude and focal mechanisms by N. Cuenot - Soultz-sous-Forêts 2000 Stimulation

Second catalogue calculated by N. Cuenot as part of his PhD thesis. The downhole network and the surface network were both used to locate events of the 2000 episode at Soultz-sous-Forêts.

The catalogue contains 265 events with a magnitude superior to 1.3, with the parameters of the two nodal plans of the focal mechanism detemined using the FPFIT algorithm (Reasenberg and Oppenheimer, 1985)(not available if mechanism not well constrained). The catalogue covers only the stimulation test and not the post-injection test of the 2000 episode. The mean location error is assumed to be less than 50 m horizontally and about 80 m vertically. [see Chapters 6 and 7 and Annexe 1 of Cuenot's Thesis].

Seismic events of the catalogue were located using a tomographic inversion method (Thurber, 1983). The method allows a simultaneous inversion to retrieve both the seismic velocity parameters and the hypocentral parameters in a 3-D layered heterogeneous medium. The location takes into account the evolution of the velocity structure at each iteration.

Time period: 30/06/2000 19:41:34 - 11/07/2000 01:14:49 (UTC).


The data parameters are the following:

Column 5: Northing from GPK1 welhead *

Column 6: Depth from GPK1 wellhead *

Column 7: Latitude WGS84 **

Column 8: Longitude WGS84 **

Column 9: Elevation WGS84 **

Column 10: Magnitude determined from the seismic signal duration

Column 11: Strike of the first nodal plan solution

Column 12: Dip of the first nodal plan solution

Column 13: Rake of the first nodal plan solution

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

** Latitude, longitude and elevation have been derived from the local coordinate system.


Remark: the signals from the Renass stations and the Güralp sensor of the surface network, and from the two hydrophones of the downhole network were not used to locate the events of the catalogue.


The description of the surface network is available ( https://cdgp.u-strasbg.fr/geonetwork/srv/fre/catalog.search#/metadata/SSFS2000-surface_network ). The signals from the RéNaSS stations and the Güralp sensor of the surface network were not used to locate the events of the catalogue.

The description of the downhole network is available ( https://cdgp.u-strasbg.fr/geonetwork/srv/fre/catalog.search#/metadata/SSFS2000-downhole_network ). the signals from the two hydrophones of the downhole network were not used to locate the events of the catalogue

The associated velocity model is available ( https://cdgp.u-strasbg.fr/geonetwork/srv/fre/catalog.search#/metadata/SSFS2000-Velocity_model_Cuenot_ 2).
