On development of crustal deformation/stress state monitoring system
Muneo Hori, Teruyuki Kato, Kenji Oguni, Takeshi Iinuma


This paper presents the stress inversion method which has been applied to the nationwide GPS network. This method determines a distribution of stress increment satisfying the equilibrium from a distribution of measured strain increment (Hori et al.,2000).We are now developing a system of monitoring crust deformation and stress state using the stress inversion method. The system will be also used in constructing a reliable model of the Japanese Islands which account for the regional heterogeneity.
