Abstract
The collapsing, the multiplet analysis, and the multiplet-clustering analyses have been applied to the microseismic data recorded during the hydraulic stimulation at Soultz-sous-Forets HDR field, France, in 1993. A seismic structure, which was growing linearly at the early stage of the stimulation, has been analysed. It is estimated that this structure represents enhanced permeable paths and consists of sub parallel microstructures, which are oriented to the directions most easy to slip by the stimulation.
