Lin, W. et al. Current stress state and principal stress rotations in the vicinity of the Chelungpu Fault induced by the 1999 Chi-Chi, Taiwan, earthquake.
As a result, interactions between the largest earthquake in a sequence, known as a mainshock, and its aftershocks may hold clues to earthquake interactions more broadly, helping to explain how changes on a fault induced by one earthquake may affect the potential site of another.
Also shown is the seismic velocity change (gray line) at the San Andreas fault, induced by the 2003 M 6.6 San Simeon earthquake (Brenguier et al. 2008a) and its synthetic velocity change (blue line).
In this study, we obtain a fault oblique ϕ at the stations along the source fault of the 1891 Nobi earthquake (Figure 4), suggesting that the process of healing would have eliminated fractures parallel to the fault strike induced by shear faulting, if produced, accompanied with the 1891 Nobi earthquake.
Because the dip of faults in the Atera fault system is nearly vertical, fault slip induced by the present state of crustal stress should be a right-lateral strike-slip, which is in contrast to the expectation based on the geological information.
After that, the low viscous fluid composed of water and the fault grains induced by fluidization decreased the frictional strength of the fault slip zone.
Therefore, shear-induced changes in transport properties must facilitate dynamic fault weakening induced by thermal pressurization.
Ground pressure consists of gravity stress and tectonic stress: sigma_{text{s1}} = gamma H + lambda gamma H = (1 + lambda )gamma H (6). Abutment stress is expressed as: sigma_{text{s2}} = (k - 1 gamma H (7). In particular, when mining approaches to faults, the rockburst induced by fault slipping takes a dominant position.
Whereafter, fine recrystallization grains were formed by the release of the stored fault energy induced by deformation at the elevated temperature.
