| Research Abstract |
Constructing models of seismogenic source faults are very significant for the estimation of seismic hazards and better understanding of crustal deformation. We constructed source fault models in Tohoku area, based on the data of tectonic geomorphology, geophysical data, such as gravity anomaly, seismic reflection profiles, hypocentral distribution, earthquake tomography, and geologic data including surface geology and bore hole data. Size and geometry of source faults are closely related to the tectonics during the back-arc rifting and opening.
