Abstract
An analytical study on the minor faults in the Miocene Arakawa Formation in the northeastern periphery of the Kanto Mountains, suggests that these minor faults were formed under the compressional stress field in the direction of NNE-SSW after the deposition and subsequent induration of the Arakawa Formarion.
However, such minor faults might be associated with the local seismic wave generated by a earthquake. Then it is necessary to extend the analytical site for clarifying the regional stress field.
