[SSS27-24] On the magnitude and heterogeneity of crustal stress

*Yoshihisa Iio1 (1.Disater Prevention Research Institute, Kyoto University)

Keywords:crustal stress, heterogeneity, seiemogenic region

The Magnitude of shear stress in the crust is one of the most important parameters in seismology, however, it has been unknown in a long time. We will infer it from dense seismic data, and further estimate theoretically whether the magnitude is large or small.
