Research Field

Mitigating Regional Earthquake Hazard Risk.

Research Overview

T. Enomoto:
Earthquake engineering, seismic engineering, urban disaster prevention engineering.

T. Inubushi:
Architectural and structural engineering.

Research Subjects

  • 1.Evaluating input seismic motion, ground tremors, and building earthquake response characteristics.
  • 2.Evaluating earthquake hazard levels.
  • 3.Seismic microzoning.
  • 4.Evaluating proficiency in earthquake preparedness.


We are conducting research and surveys on the association between ground structure and building damage, and investigating regional disaster prevention countermeasures. We are also investigating disaster risk mitigation methods related to earthquake hazards considering disaster prediction and disaster prevention countermeasures by using software and hardware methods.

We focus on the main areas of earthquake engineering and urban disaster prevention engineering. Recent years have seen large earthquakes around the world. Japan suffered the Great Hanshin Earthquake in 1995, the Chuetsu earthquakes in Niigata in 2004, the Fukuoka western offshore earthquakes in 2005, the Noto Peninsula earthquake in 2007, and the Chuetsu offshore earthquake in Niigata in 2007. Overseas, we have seen the 1998 earthquake in Turkey, the 1999 Jiji earthquake in Taiwan, the 2007 Sichuan earthquake in China, and the 2008 L'Aquila earthquake in Italy. The 2011 Tohoku offshore earthquake was particularly disastrous in terms of loss of life and damage to buildings because of the subsequent tsunami. Earthquake hazards show a significant correlation between the geological conditions and the mechanisms that trigger earthquakes, and the properties of buildings. These earthquake hazards have provided important lessons in developing quake-resistant technologies, and effective disaster prevention information and countermeasures. We are researching hazard prediction methods, disaster prevention countermeasures, and management systems for disaster prevention information, including the mechanisms that trigger earthquakes, causes of damage to the ground and buildings, and the use of disaster prevention information to develop countermeasures for tsunamis. We have reported the results of "Research on building an integrated software/hardware risk management system for mitigating disaster risk", which is proving useful in creating future disaster countermeasures.
