Effective Use of Cell Broadcast Service (CBS) by Disaster Type

Abstract

The purpose of this study is to determine in which situation the recipient of the message perceived if a disaster text is appropriate, depending on the situational requirements of the disaster text provided to the recipient. Disaster situations given for analysis include predictable disasters (heavy rains, heavy snowfalls), momentary disasters (earthquakes, landslides), and spreading disasters (epidemics, gas leaks). The recipients were asked to evaluate the risk, urgency, and relevance of the disaster and their effects on the perceived appropriateness of the disaster message was analyzed through multiple regression. It is found that they perceived predictable disasters as appropriate when relevant, momentary disasters when urgent, and spreading disasters when dangerous or urgent. These findings confirmed that differential criteria for classifying disaster text messages by disaster type can effectively deliver information to the recipient. It is necessary to improve the standards for distributing disaster texts as a more reliable means of communication, considering a growing number of disaster-like situations such as earthquakes, fire events, and fine dust problems.
