Parallel simulation of strong ground motions during recent and historical damaging earthquakes in Tokyo, Japan
The development of high-performance computing facilities such as the Earth Simulator supercomputer and the deployment of dense networks of strong ground motion instruments in Japan (K-NET and KiK-net) have made it possible to directly visualize regional seismic wave propagation during large earthquakes. Our group has developed an efficient parallel finite difference method (FDM) code for modeli...
متن کاملLarge-scale broadband simulation of strong ground motions from recent and historical damaging Earthquakes in Japan
A recent development of the Earth Simulator super parallel computer has made it possible to realized realistic 3-D simulations of high-frequency seismic wave propagations on a regional scale. Paralleling this development, the deployment of dense networks of strong ground motion instruments in Japan (K-NET and KiK-net) has now made it possible to directly visualize regional seismic wave propagat...
متن کاملWavelet-based Analysis for Pulse Period of Earthquake Ground-motions
Pulse period of earthquake records has been known as a key parameter in seismology and earthquake engineering. This paper presents a detailed characterization of this parameter for a special class of earthquake records called pulse-like ground motions. This type of motions often resulting from directivity effects is characterized by a strong pulse in the velocity time history of motion, in norm...
متن کاملHydrodynamic pressures on sloping dams during earthquakes. Part 2. Exact theory
The equations for the earthquake forces on a rigid dam with an inclined upstream face of constant slope are solved exactly by two-dimensional potential-flow theory. The distribution of the hydrodynamic pressure along the upstream face and the total horizontal, vertical and normal loads on the dam are computed from the integral solutions. The results obtained from the exact theory are compared w...
متن کاملSimulation of Strong Ground Motions
The estimation of potential strong ground motions at short epicentral distances (J1 = 10 to 25 km) resulting from large earthquakes, M;;;; 6.5, generally requires extrapolation of a limited data set. The goal of this project has been to quantify the extrapolation through a simulation technique that relies heavily upon the more extensive data set from smaller magnitude earthquakes. The simulatio...
