Description

In order to elucidate the relationship among crustal velocity structures, micro seismic activities, active faults, geologic structures and the deep structure of the Philippine Sea Plate, we analyzed three seismic explosion survey records conducted in the Kinki district, considering compatibility of all profiles. We use the wide-angle reflection and refraction methods to obtain reflection sections and velocity structures along the profile lines. Comparison of the seismic velocity structures with other data, we can find horizontal reflectors beneath the seismogenic layer, dipping reflectors in the lower crust under large faults, concentration of micro earthquakes in a layer in which P-wave velocity is 5.8-6.4km/s.
