Light-Weight Safety Confirmation System for Large-Scale Disasters

We have been developing and operating safety confirmation systems for universities since 1999. The Great East Japan Earthquake in 2011 clarified some issues related to the safety confirmation systems. Thereby, we reviewed the safety confirmation systems, the result of which revealed that more carefully selected functionality, restriction on the volume of communication, and enhanced anti-disaster feature of the systems would be required. We have then developed the light-weight safety confirmation system that does not have the function to simultaneously transmit mass emails and is designed for easier system migration. Evaluation was conducted by performing demonstration experiments of the newly developed safety confirmation at a disaster prevention drill of a university.
