One of the causes of enormous damages of the 2011 megathrust Tohoku earthquake (M 9.0) was the underestimation of the first tsunami warning, which was issued three minute [...]

The 2014 Nagano prefecture Kamishiro fault Earthquake of magnitude 6.7 occurred on November 22, which jolted central mountainous area in Japan. The maximum seismic intens [...]

We have collected a lot of boring exploration and physical property data (mainly microtremor observation ones) in the past, which are important to especially evaluate sei [...]

We develop an automatic system for generating the optimal mesh model based on the adaptive mesh refinement method and the tsunami propagation simulation code adapted for [...]

This paper deals with earthquake safety of the brick chimney of the height of 23 m in Tokoname, Japan. We measured micro-tremor to acquire vibration characteristics, whic [...]

Strong ground motion simulation based on 2-dimensional finite element method considering topographic effects, local site effects of sedimentary layer and soil-structure i [...]

We attempted to illustrate the building damage in the central region of Anamizu town by characteristics of earthquake ground motion and subsurface structure. We conducted [...]

We examine source characteristics of intraslab earthquakes based on eleven source models estimated by the empirical Green’s function (EGF) method. The asperity source m [...]

In environmental vibration evaluation, a simple evaluation technique based on sub-structure-type lumped mass model is proposed. The technique was applied to real site to [...]

We study characteristics of long-period ground motions from the 2003 Tokachi-oki earthquake (Mj 8.0), a large interplate earthquake, based on spatial distribution maps an [...]
