... mechanisms are dominated by shearing (Stanek and Eisner, 2013; Rutledge et al. 2013). Each source mechanism of a shear event represents an (micro)earthquake with two potential fault planes and slip on these planes. According to a type of stress regime in the source area we observe different types of source...
