We investigated the disagreement of predicted long period ground motion using two 3D velocity models and searched for the cause of this disagreement in the 3D models. VE of the predicted long period ground motions by Tokai-Tonankai Earthquake vary 50-100 cm/s in period of 5-10s at Yokohama, Shinjuku and Chiba. Different models of seismological bedrock at basin edge and basin structure in Sagami-bay produce the disagreement of the calculated ground motion. For now, several 3D models are proposed, which shall be compared and the differences of predicted long period ground motions shall be grasped from the point of view of structural response.
