Simplified regression models to predict the site amplification are widely adopted to seismic hazard maps, building codes, etc. In practice, the most popular parameters to [...]

Effectiveness of the existing simplified method for evaluating liquefaction potential under ocean trench long duration earthquakes is investigated. Effective stress analy [...]

Many active foldings are found and it is known that the subsurface structure is complex in the Niigata-ken Chuetsu area, Japan, where two destructive earthquakes were occ [...]

Many petroleum tanks were damaged by sloshing during 2003 Tokachi-oki, Japan. Large earthquakes are predicted to occur within 50 years, which will cause the similar damag [...]

Many houses and infrastructures were damaged during the 2004 Niigata-ken Chuetsu earthquake and the 2007 Niigata-ken Chuetsu-Oki earthquake in Japan. Distribution of peak [...]

The design earthquake motions are often defined by the response spectra. For example, in the seismic design standard for the Japanese Railway facilities (1999) there are [...]

An element refinement algorithm based on sensitivity analysis is proposed and applied to kinematic source inversion analysis. The high sensitivity element on a target fau [...]

The characteristics of seismic wave energy are examined in this study. The attenuation equation of total seismic wave energy with respect to moment magnitude and hypocent [...]
