Microseismic catalogue of the 2003 episode at Soultz-sous-Forêts calculated by M. Calò and C. Dorbath using the surface network. Number of events: 4728. The catalogue was used to perform a time-dependent (4-D) seismic tomography. It covers all the five phases of the 2003 experiment program. The location of events was performed using an automatic procedure for detecting and picking the seismic phases. About 7500 triggers were detected and 4728 events were finally located using at least eight P- and three S-arrival times with a root mean square (rms) lower than 0.04 s. Time period: 27/05/2003 18:37:50 - 12/07/2003 20:31:00 (UTC time). The data parameters are the following: Column 1: Event ID Column 2: Date (UTC) Column 3: Time (UTC) Column 4: Latitude WGS84 Column 5: Longitude WGS84 Column 6: Elevation WGS84 Column 7: Magnitude Column 8: RMS Last update of data: 13/09/2019

Velocity model used by M. Calò and C. Dorbath. The velocity was derived from sonic logs operated by Schlumberger in GPK1 (https://cdgp.u-strasbg.fr/geonetwork/srv/fre/catalog.search#/metadata/SSF-GPK1) and from transit times for shots fired inside GPK1 at different levels and recorded on the IMRG downhole network (Beauce et al., 1991). The catalogue of events located during 2003 stimulation using the downhole and the surface network is available here (https://cdgp.u-strasbg.fr/geonetwork/srv/fre/catalog.search#/metadata/SSFS2003-catalogue).

Velocity model described in B. Dyer's report. Used in particular to calculate location of microseismic events from the downhole network during 2004 and 2005 stimulation. The catalogue of events located during 2004 stimulation using both the downhole network is available (https://cdgp.u-strasbg.fr/geonetwork/srv/fre/catalog.search#/metadata/SSFS2004-catalogue_downhole). The catalogue of events located during 2005 stimulation using both the downhole network is available (https://cdgp.u-strasbg.fr/geonetwork/srv/fre/catalog.search#/metadata/SSFS2005-catalogue_downhole).

Before the 2003 episode, a permanent network designed to monitor the microseismic activity at Soultz-sous-Forêts was installed by EOST (Ecole et Observatoire des Sciences de la Terre) from the Strasbourg University. It consisted of nine stations, six one-component and three three-component sensors. The network was operational just before the 2003 stimulation of GPK3 (https://cdgp.u-strasbg.fr/geonetwork/srv/fre/catalog.search#/metadata/SSF-GPK3). A temporary network of fourteen seismometers (six three-component and eight one-component) was added to this permanent network. Contrary to the 2000 episode, all the fourteen stations of the temporary network were continuously recording. In addition to the network under the responsibility of EOST, a broad-band Güralp sensor was used mostly for waveform analysis. Two other accelerometers completed the surface monitoring system too. The coordinates of the stations have been obtained from RESIF (https://www.resif.fr/">https://www.resif.fr). Last update of data: 03/02/2020

Seismological signals acquired around Soultz-sous-Forêts during the 2010 circulation Episode. Waveforms from the permanent stations described in SSFC2010-Surface_network (https://cdgp.u-strasbg.fr/geonetwork/srv/eng/catalog.search#/metadata/SSFC2010-Surface_network) are provided for each event from SSFC2010-Catalogue (https://cdgp.u-strasbg.fr/geonetwork/srv/eng/catalog.search#/metadata/SSFC2010-Catalogue), (-30s, +90s).

Seismological signals acquired at Soultz-sous-Forêts during the 2003 Stimulation episode. The waveforms were recorded by a downhole and a surface seismological network during the hydraulic stimulation of well GPK3 (https://cdgp.u-strasbg.fr/geonetwork/srv/fre/catalog.search#/metadata/SSF-GPK3) and the circulation test betweeen GPK2 (https://cdgp.u-strasbg.fr/geonetwork/srv/fre/catalog.search#/metadata/SSF-GPK2) and GPK3. The downhole seismological network consisted of 6 stations and the surface network of 25 stations. The complete description of the downhole seismological network is available (https://cdgp.u-strasbg.fr/geonetwork/srv/fre/catalog.search#/metadata/SSFS2003-downhole_network). Up to now, there are only data for 4550 station. The complete description of the surface seismological network is available (https://cdgp.u-strasbg.fr/geonetwork/srv/fre/catalog.search#/metadata/SSFS2003-Surface_network).
