... not be used to estimate stress magnitudes. The orientation of the maximum horizontal principal stress (S Hmax ) is determined to be NE-SW to -2000 mbsf, subparallel to the subduction margin between Philippine Sea plate and Eurasian plate. We attempt to estimate stress magnitudes assuming that the stress state...

... that contribute to low stress magnitudes. As a way to confirm the inference, we examine the attitudes of Quaternary faults with respect to the current stress field. A majority of the faults are oriented in the optimal directions for slip, as indicated by the overall high ratios of shear to normal stress acting...
