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 [...]

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 [...]

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 [...]

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 [...]
