%T Characteristics of microseismic events with large magnitude collected at Cooper Basin, Australia and Basel, Switzerland
%X The authors analyzed microseismic events with large magnitude collected during and after hydraulic stimulations at Cooper Basin, Australia in 2003 and Basel, Switzerland in 2006. The large events at Cooper Basin can be interpreted by a slip of single asperity at the edge of the stimulated zone. The large events from the middle and deeper parts of the stimulated zone at Basel can be interpreted by shear slip of single/multiple asperities, and the shallow large events, of which hypocenters are spatially independent from the seismic cloud, were very likely to occur in sub-parallel fracture to the main seismic cloud.
