WebThis hypothesis neatly explained much of the phenomenology of earthquakes, including the Gutenberg-Richter law, the scale-invariant distribution of faults, the relatively low and constant stress drop, the ease with which small natural and man-made stress perturbations can induce earthquakes, and the long-term stationarity inferred for seismic ... WebAbstract Three-dimensional fault interpretation is a time-consuming and tedious task. Huge efforts have been invested in attempts to accelerate this procedure. We present a novel workflow to perform semiautomated fault illumination that uses a discontinuity attribute as input and provides labeled fault surfaces as output. The procedure is modeled after a …
