... Archipelago, Japan with an emphasis on earthquake prediction utilizing the variations of stresses in the earth's crust. Introduction In-situ stresses are of great importance for the design and stability assessment of rock engineering structures. There are many in-situ stress inference techniques classified...

... Abstract In this paper we use three-dimensional spherical shell finite element model of power-law creep mechanism, to analyze the stress field variation in china mainland caused by the brittle failure of Longmenshan fault, during 5.12 Wenchuan earthquake. We establish a local coordinate system...

... earthquakes occurred on the boundaries of high- and low-V anomalies in the upper mantle, suggesting that the crustal large earthquakes of the region are related to the upper-mantle structure. These results could be helpful to better understand the rock stress around the source areas. Introduction...

... 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 In-situ rock stress measurement was carried out in the Kamaishi mine of lwate prefecture to quantify the variation of the shallow crustal stress field associated with the 2011 Tohoku-oki earthquake. Stress measurement was conducted by the Compact Conical-ended Borehole Overcoring...

... of storage through seismic relocation. The result indicates the relationship of seismicity and the importance of tectonic stress field on understanding the role of Coulomb Stress Change in triggering devastating earthquakes. Introduction To deeply understand the triggering role of reservoir in seismicity...
