Protects lives and businesses from natural disasters

The Center for Safety and Reliability Engineering pursues research and development to protect the lives and businesses of customers and provide safety and reliability in natural disasters such as earthquakes, tsunamis, torrential rains, and strong winds. Large earthquakes such as the Great East Japan Earthquake and the Kumamoto earthquakes continue to occur. There are also concerns about the risk of a major earthquake directly beneath a metropolitan area or the Nankai and Sagami Troughs in the future. The impact of global warming is also increasing the risk of massive typhoons and localized torrential rains. The center engages in research and development to protect lives and businesses from such disasters from three perspectives: The soft aspects (of risk forecasting and diagnostic technology), the hard aspects (of technology to minimize damage), and the skills aspect (of technology to assist with rapid response after a disaster has occurred).

Soft Aspects
(of risk forecasting and diagnostic technology)

To minimize damage from disasters, it is first important to know what the risks are. The center has developed proprietary forecasting technology such as seismic motion prediction, tsunami analysis, prediction of building damage from an earthquake, prediction of flooding during torrential rainfall, and evacuation simulations, and has been instrumental in evaluating the many risks for various kinds of facilities with a high degree of accuracy.

Hard Aspects
(of technology to minimize damage)

Various kinds of damage occur, depending on the disaster situation and the facility conditions. We are conducting many types of research and development on seismic isolation and vibration control technology to minimize the damage from building shaking and swaying, earthquake-resistant construction methods for ceilings and equipment, tsunami protection technology, and other technologies that we can propose for each facility, depending on the needs.

Skills Aspects
(of technology to assist with rapid response after a disaster)

Immediately after an earthquake has occurred, it is very important to rapidly assess conditions and respond, to aid businesses in a rapid recovery. The center also develops technologies to assist with a smooth response after a disaster, such as transmission of information and control of equipment via Earthquake Early Warnings, and structural health monitoring of buildings after an earthquake, etc.
