Abstract

This study analyzes the relevance of the mobile communication network frequently used disaster alert devices. Recently, types of emergency equipment are being diversified according to the types of disasters and the transfer devices can do multiple transfer its information with the advancement of broadcast and communication technologies. The main subject of establishing the system can select broadcasting equipment and transmission media according to the type and spot of the disaster information broadcasts. Natural disasters such as heavy rain, storms, and snowfall based on pre-observed information are broadcasted, which helps predict disaster-response times to assure the safety of citizens. But natural disasters such as earthquakes can only be observed by special equipment. It raises a question if information on direct seismic waves except for the tsunami disaster can be transferred to an alert system. This is because the time which is in connection with the arrival time information corresponding to the seismic intensity of an earthquake and its location as well as the time transmitted to the respective alarm devices varies. To address these issues, this study cross-compared to the transmission time based on the widely-used communications method of a disaster warning system. Also, the study identified that the location of the TTS engine determine different information transmission and seeks to provide solution for improvement.
