IISEE Research Projects
Study on Strong Motion Observation for Buildings and Its Diffusion (2006.4--2009.3)
Building Research Institute (BRI) has been conducting strong motion observation for buildings since 1957. Currently, 74 stations are in operation in the BRI network. In 2007, a 37-story building in Tokyo was instrumented to investigate characteristics of long-period ground motion and response of high-rise buildings. The database system of the strong motion records is available at

Development of International Network of Technical Cooperation for Earthquake Disaster Mitigation of Buildings and Urban Areas in Developing Countries (2006.4--2009.3)
This study made the effort to create a network of international technical cooperation for earthquake disaster mitigation of buildings and urban areas
in developing countries by utilizing web-based communication tools such as earthquake disaster database, damage estimation system, archive of electric lecture notes, e-learning system, video conference system and others.

IISEE's CMTs, Aftershock Distributions, Fault planes, and Rupture processes for recent large earthquakes in the world (2005.4--2008.3)
We determined centroid moment tensors, aftershock distributions, fault planes, and rupture models for large earthquakes that occurred since 1994 on the globe. We made a catalog consisting of the above earthquake information and information issued by other organizations. We developed a database of this catalog, and the software by which the catalog is searched. In addition, we develop software to perform strong ground motion simulation for seismic bedrock using a stochastic Green's function method.

Survey Methods for Earthquake Disaster Related with Buildings and Houses
This research theme is a part of the national research project "Development of Earthquake and Tsunami Disaster Mitigation Technologies and Their Integration for the Asia Pacific Region (EqTAP)."
The followings have been conducted in this research by means of knowing and systematizing the actual situation of the methods and examples of earthquake disaster surveys and studies. These are: Ordering required input data, means and purposes of survey and study; Making clear things that shall be done in research stage before earthquake and in emergency stage after earthquake; Sharing results and information with participating countries.
"Guideline for Damage Survey Methods of Earthquake Disaster Related with Buildings and Houses" has been issued as a part of results from this project.
Information Network on Earthquake Disaster Mitigation Technologies
Earthquakes cause severe disasters almost every year around the world. The recent earthquakes in Kobe in 1995, Turkey and Taiwan in 1999, and India in 2001 resulted in significant loss of human lives, buildings, and infrastructures. Technical countermeasures for earthquake disaster mitigation are therefore required in all earthquake-vulnerable countries.
The IISEE (International Institute of Seismology and Earthquake Engineering) has initiated a research project entitled "Information Network on Earthquake Disaster Mitigation Technologies." This project is expected to contribute to disaster mitigation efforts in earthquake-vulnerable countries by accumulating and disseminating valuable technical information.
Interim results of the project are available on the Web page.
