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 کاملLarge-scale parallel simulation of seismic wave propagation and strong ground motions for the past and future earthquakes in Japan
Large-scale parallel finite-difference method (FDM) simulations of seismic wave propagation have been conducted using the Earth Simulator in order to clarify the complex seismic wavefield resulting from heterogeneities in structures and the source rupture process during the Hyogo-ken Nanbu (Kobe) earthquake (Mj 7.2; Mw 6.9) in 1995. High-resolution simulation using 240 nodes (1920 processing el...
متن کاملA new probabilistic seismic hazard assessment for greater Tokyo.
Tokyo and its outlying cities are home to one-quarter of Japan's 127 million people. Highly destructive earthquakes struck the capital in 1703, 1855 and 1923, the last of which took 105,000 lives. Fuelled by greater Tokyo's rich seismological record, but challenged by its magnificent complexity, our joint Japanese-US group carried out a new study of the capital's earthquake hazards. We used the...
متن کاملReturning-Home Analysis in Tokyo Metropolitan Area at the time of the Great East Japan Earthquake using Twitter Data
This paper clarifies the occurrence factors of commuters unable to return home and the returning-home decision-making at the time of the Great East Japan Earthquake by using Twitter data. First, to extract the behavior data from the tweet data, we identify each user’s returning-home behavior using support vector machines. Second, we create non-verbal explanatory factors using geotag data and ve...
