... ABSTRACT Knowledge of stresses is an important component of any geomechanical design task. This requirement is accentuated in deep mines, where stresses not only lead to fracturing around excavation boundaries, but include induced seismicity and the associated problems of strainbursting and rockbursting...

... Abstract This study concerns dynamic simulations of earthquakes and the seismicity associated with induced slip of preexisting fractures in the rock mass for a repository for spent nuclear fuel planned to be constructed at Forsmark, Sweden. We use Particle Flow Code 2D (PFC 2D ) to model...

... Abstract We derived a tectonic stress field model in the vicinity of the source area of the Mw9.0 Northeastern Japan Earthquake from modeling seismicity and analyzing earthquake focal mechanisms before and after the mainshock. There are 5 large earthquakes (Mj>7.0) occurred in the source...

...-constrained diffusivity is the key factor in computation of pressure seepage as well as reservoir-triggered seismicity, while the elastic stress field also have a certain effect on the pore-pressure. Meanwhile, coupling computation is needed between elastic stress field introduced by reservoir loading...

... ABSTRACT: A model of the tectonic stress state of Longmenshan Faults and adjacent area including direction and magnitude is derived from the spatial and temporal distribution of seismicity before and after Wenchuan Ms 8.0 earthquake. This technique utilizes the assessment of spatial...
