J.D. Byerlee V. Kuksenko A. Ponomarev A. Sidorin D.A. Lockner 1991 The failure process in a brittle granite sample can be stabilized by controlling axial stress to maintain a constant rate of acoustic emission. As a result, the post-failure stress curve can be followed quasistatically, extending to hours the fault growth process which normally would occur violently in a fraction of a second. Using a procedure originally developed to locate earthquakes, acoustic emission arrival-time data are inverted to obtain three-dimensional locations of microseisms. These locations provide a detailed view of fracture nucleation and growth. application/pdf 10.1038/350039a0 en Springer Nature Quasi-static fault growth and shear fracture energy in granite article
