The Kinki triangle, central Japan, is marked by a dense distribution of active faults. For regional characterization of the crust in the Kinki metropolitan area to be used for seismic hazard mitigation, seismic reflection profiling was carried out us

To reveal a subsurface structure beneath the southern part of the Boso Peninsula, Japan, where the Philippine Sea plate is subducting and great interplate earthquakes associated with the subduction occur repeatedly, we conducted a new seismic reflect

Nappe structures at different scales have been reported from many orogenic belts in the world, but almost all the examples are old, inactive structures. Under conditions of low erosion rate and/or high tectonic strain rate, active nappes are expected

S-wave information, in conjunction with conventional P-wave, may quantitatively delineate reservoir condition and has progressively been playing important roll in recent oil/gas exploration and development. A reflection seismic method using PS conver

We review seismic interferometry with an example of a numerical simulation. A cross-correlation of two seismic records at different receivers yields a virtual source record that corresponds to the seismic response observed at one receiver due to the

The northern Fossa Magna (NFM) basin is a Miocene rift system produced in the final stages of the opening of the Sea of Japan. It divides the major structure of Japan into two regions, with north-trending geological structures to the NE of the basin

A new ray-tracing method called linear traveltime interpolation (LTI) is proposed. This method computes traveltimes and raypaths in a 2D velocity structure more rapidly and accurately than other conventional methods. The LTI method is formulated for
