We apply a Hamiltonian particle method, one of the particle methods, to simulate seismic wave propagation in a cracked medium. In the particle method, traction free boundaries can be readily implemented and the spatial resolution can be chosen in ...

Scaling is a key phenomenon for understanding of subsurface or sub-seafloor hydrothermal circulation. Our goal in this study is to evaluate the importance of both chemical kinetic and hydrodynamic effects on silica deposition. For qualitative and ...

In this study, we developed a code to deal with two kinds of three-dimensional (3D) inversion schemes for the analysis of self-potential data (SP). One is for the transient SP data under saturated condition, and the other is for the SP data under ...

We evaluated three-dimensional (3D) resistivity structure using marine controlled-source electromagnetic (mCSEM) data obtained around hydrothermally active Iheya north area, offOkinawa, Japan. To handle complex submarine topography around the targ...

Coda-Q is a stochastic parameter reflecting the heterogeneities of medium that seismic waves travel through. We confirmed that coda-Q would vary with the stress loaded to an elastic medium using numerical simulations of seismic wave propagation. W...
