000018376 520__ $$2eng$$aIntegrated earthquake simulation (IES) is a seamless simulation of analyzing the seismic wave propagation process and the structural seismic response process. A model of high fidelity is constructed for an urban area; a three-dimensional model of underground structures is used for the seismic wave propagation process, and a non-linear model is constructed for each building or structure which is located in a target area. Large-scale numerical computation is inevitable for these models of IES; for instance, the underground structure model has more than 100,000,000,000 degree-of-freedoms and the number of the structures is of the order of 100,000. High performance computing is thus employed. Demonstrative examples of IES which are obtained by using K computer, the world 4th fastest supercomputer, are presented. The target is Tokyo which is threatened by a next Tokyo Metropolis Earthquake. Explained are two simulations of analyzing the ground motion amplification process that accounts for non-linear soil properties, and analyzing the seismic responses of residential buildings the models of which are automatically constructed by using available digital data. The possibility of making hazard and disaster assessment using IES is discussed based on these examples.
