Simulation of near-source ground motion during the 1995 Hyogo-ken
Nanbu earthquake
by 3D FDM using a source model obtained by the
waveform inversion and 3D velocity structure estimated from the
results of seismic prospectings.

ground velocity. A band shaped area of strong ground motion is seen
in downtown Kobe city.
