The advancement of computer hardware has made it possible to make large scale simulations of earthquake disasters and human actions, in high spatial and temporal resolutions. We utilize high performance computational resources to simulate the time critical mass evacuations like those triggered by a tsunami, and the recovery process of lifeline networks after a major earthquake. Due to various limitations, the existing methods either use simple models or empirical relations. We are developing fine detailed models, to overcome these limitations. Also, we seek to improve PDS-FEM, which a numerical technique for 3D crack propagation simulations, and apply to explore various crack propagation phenomena.
