- Basic study on high resolution seismic disaster estimation of cities under multiple earthquake hazard scenarios with high performance computing
抄録
We develop a system to perform many cases of earthquake disaster estimations of large cities. By using such a system, we aim to make disaster estimations considering uncertainties in earthquake parameters such as the source or velocity structure. Soil amplification analysis and structural response analysis are combined for reflecting soil/structural properties to disaster estimation. The major bottleneck of the previous system for application to large number of cases in large areas was the large file I/O that linearly increases with respect to the number of cases. We make remedies to these bottlenecks to improve the scalability. Application shows that 100 case simulations with different input waves targeted on area with 0.25 million structures can be performed using high performance computers.
