~Providing 3D Velocity Models for Ground Motion Simulation~

Since Great Hanshin earthquake, Japan, 1995,JGI has conducted many refraction and reflection seismic surveys providing not only subsurface structural information but also velocity models down to the depth of earthquake basement. These models are very useful simulating the ground motion when natural earthquakes occur.
