Abstract (in english)
   The geothermal reservoir at Soultz-sous-Forets is a valuable natural laboratory for understanding the mechanisms of microearthquakes generated during stimulations and circulation tests. An ongoing effort currently exists regarding the retrieval of mechanisms aimed to indicate the type of fracturing of the rock massif. As a default, a moment tensor description has been applied. Nevertheless, the retrieval of the mode of fracturing still remains ambiguous. Recent studies indicate a prevailing shear slip but, rarely, a non-shear pattern has also been observed. The moment tensor, used today as a universal tool for descriptions of the mechanism, captures general balanced dipole sources.The geothermal reservoir at Soultz-sous-Forets is a valuable natural laboratory for understanding the mechanisms of microearthquakes generated during stimulations and circulation tests.
