It is extremely important to quickly assess the damage immediately after an earthquake for providing suitable disaster response. We has constructed prototype of a real-ti [...]

We describe three achievements for a ground motion simulation. First, we propose a kinematic modeling in which rupture delay time is governed by an eikonal equation on Ri [...]

This paper proposes a method to have a whole picture of earthquake damage rapidly and accurately as a post-earthquake damage assessment. In Japan, strong ground motion ob [...]

The National Seismic Hazard Maps for Japan （NSHMJ） are issued by a governmental organization, the headquarters for earthquake research promotion of Japan, to estimate [...]

To investigate fault modeling in the Off shore Fault Evaluation Group, the Japan Agency for Marine-Earth Science and Technology (JAMSTEC) has collected marine seismic ind [...]

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 made a velocity structure model for Tsukuba area in Japan. The velocity model was based on a geological model and was developed by using microtremor surveys and its H/ [...]

We apply the strong-motion prediction method ‘Recipe’ summarized by the Headquarters for Earthquake Research Promotion of Japan to the simulation of ground motions du [...]

The Japan islands are in a complex tectonic setting with various subducting plates, and most of their urban areas are located on sedimentary basins. These lead to three-d [...]
