Enhancement of Integrated Earthquake Simulation With High-Performance Computing

Abstract

Integrated earthquake simulation (IES) is a system to estimate possible earthquake hazard and disaster which can take place in an urban area by means of seamless numerical computation. High-performance computing (HPC) is enhanced so that IES is able to simulate a larger area in a shorter time, by improving the system architecture and adding new elements which smoothens the system's efficiency. It is shown in numerical experiments (which are carried out for actual urban areas) that the performance of IES enhanced with HPC is satisfactory. A new system is developed to generate a hazard map which depicts earthquake damages in higher spatial resolution by taking advantage of IES enhanced with HPC. It is shown that such maps can be generated for Tokyo metropolis in half a day.

Application of HPC to Earthquake Engineering - Seismic Structure Response Analysis and Urban Area Earthquake Simulation

“…The progress of computer hardware and software is solving this difficulty. In this section, we briefly mention a system, called Integrated Earthquake Simulation (IES) [4,15,16], which uses a set of numerical analysis methods for urban area earthquake disaster assessment, and present two examples of the numerical analysis methods which are put in the system.…”
