Keywords:ESR analysis, Gomura fault zone, Yamada fault zone

As a part of a research project commissioned by Secretariat of Nuclear Regulation Authority (S/NRA/R), to organize information about evaluation techniques of active faults, we executed topographical and geological explorations along the Gomura and the Yamada fault zone. Here, we show the fault rocks observed in outcrops and core samples, and results of Electron Spin Resonance (ESR) analyses in them.
