Localisation Pitfalls of Seismic Events Due to Anisotropy – A Real Data Case Study

P093 Summary LOCALISATION PITFALLS OF SEISMIC EVENTS DUE TO ANISOTROPY – A REAL DATA CASE STUDY K. SOMMER 1 D. GAJEWSKI 1 and R. PATZIG 2 1 Institute of Geophysics University of Hamburg Germany 2 Department of Geophysics Charles University Prague Czech Republic The environment of the German Continental Deep drilling site (KTB) is known to be anisotropic. In this study we have analysed the seismic events generated by the KTB long term injection experiment. More than 2500 seismic events were generated and about 260 events were recorded by the borehole geophone and by the 42 station surface array centred
