Protects lives and businesses from natural disasters

There are concerns about an earthquake directly beneath the Greater Tokyo Area, massive earthquakes in the Nankai and Sagami Troughs, occurrence of other major earthquakes, and the damage caused by torrential rains, typhoons, and other meteorological events is also increasing. To protect lives and businesses from such disasters, the Center for Safety and Reliability Engineering is pursuing research and development from the three perspectives of the soft aspects (risk prediction, diagnostic technology), the hard aspects (earthquake resistance, seismic isolation, vibration control, and other damage mitigation technologies), and skills (technology that increases resilience in the face of disaster).

Soft Aspects
(risk prediction, 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 (earthquake-resistance, seismic isolation, vibration control, and other damage mitigation technologies)

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 (technology that increases resilience in the face of 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.
