Injection 2003 in HDR site Soultz-sous-Forets: microearthquake mechanisms and stress pattern
Original language description
Stress evaluation is an immediate benefit of determination of fault-plane solution of events that occur on pre-existing faults within a zone of interest. We have retrieved the moment tensors of 45 microearthquakes with magnitudes between M=1.4 and 2.9 which occurred during the 2003 massive fluid injection in the borehole of the Soultz HDR-site. Surprisingly, the mechanisms were predominantly pure shear slips, i.e. with source mechanisms typical for tectonic earthquakes. To estimate the stress state within the zone of the hypocentra, we applied the approach of Angelier (2002), minimizing the slip shear stress component, advantageously avoiding a prior discrimination between fault and auxiliary plane.
