Proposal for Safety Confirmation System That Launches Bulletin Board Automatically

There are many cases where large-scale damage occurs owing to the occurrence of disaster. At the time of the Great East Japan Earthquake in 2011, there was huge damage occurring over a wide area, not only in the Tohoku (NorthEast) Region with the epicenter, but the damage also extended to the Kanto Region. This earthquake disaster caused extensive damage also to information/telecommunication infrastructure, which is the important li feline for people's daily life. Information/communication equipment became unable to use due to the line disruption, blackout, etc. [1]. Thus, in order to be prepared for such a situation, it is considered to be quite important to perform safety confirmation at the time of natural disaster.
