Velocity model described in J. Helm thesis (p.127) according to Beauce et al. (1991). The velocity model was used to calculate location of microseismic events from the surface network during 1993 stimulation. The catalogue of events located during 1993 stimulation using the surface network is available (https://cdgp.u-strasbg.fr/geonetwork/srv/fre/catalog.search#/metadata/SSFS1993-catalogue_Helm).

The surface network during the 1993 episode consisted of 14 stations. Three of them were permanent seismic stations, since removed. Eight of them were temporary 1-component seismometers. The station 1 was moved two times and the station 3 one time during the episode to improve azimuthal coverage. At least, three temporary 3-component seismometers were installed at four different sites. The surface network was installed by EOPGS (Ecole et Observatoire de Physique du Globe de Strasbourg).166 events were detected with the network. The catalogue of seismicity associated is available (https://cdgp.u-strasbg.fr/geonetwork/srv/fre/catalog.search#/metadata/SSFS1993-catalogue_Helm). Unfortunately the waveforms have not been recovered. Last update of data: 07/03/2018
