[Case Study] The first comprehensive integrated earthquake disaster prevention system in a complex facility.

A system has been established to accurately support quick initial responses before the shaking arrives, based on emergency earthquake alerts and building integrity assessments!

**Overview** ■Purpose: Assessment of building integrity ■Category: Measurement, Earthquake Disaster Prevention, Emergency Earthquake Alerts ■Related Products: VissQ, Emergency Earthquake Alert System ■Scope of Provision: System design, complete equipment set, installation and adjustment, maintenance **Background and Issues** At the Tokyo Distribution Center, during the aftershocks following the Great East Japan Earthquake in 2011, it became difficult to determine whether tenants who temporarily evacuated outdoors could re-enter the building. Therefore, there was a need to establish a system that could quickly provide information on the safety of the building. **Provided System** By installing seismometers in each building, we visualize the building's vibrations and provide the system "VissQ," which supports the safety and security of people and buildings during an earthquake. By adopting the most suitable assessment methods and criteria for each building, we enhance the speed and accuracy of safety assessments, enabling precise initial responses during disasters. **Effects After Implementation** - Objective judgments regarding entry into the building during an earthquake are now possible. - Quick responses, such as explaining the situation to building users and establishing initial response systems for inspections and recovery, are now achievable. - As a response to individuals unable to return home, it is now possible to determine the feasibility of opening temporary accommodation facilities within approximately six hours after a disaster, based on guidelines.
