We propose to analyse the microseismicity induced by the four different stimulations
carried out at the geothermal site of Soultz-sous-Forêts. Since different strategies
of injection have been used, the behaviour of the seismicity can be detailed and some
hypothesis about the relation between seismicity and stimulation may be assessed.
This discussion will involve tomographic results, faulting mechanisms and
spatio-temporal distribution of the seismicity. We will also point out some relations
between the physical properties of the reservoir and the evolution of some
seismological parameters (velocity, etc.).
