A case study of utilization of L-alert for providing life support information during the emergency restoration period

Abstract

L-alert is an information sharing system widely used for evacuation order transmission. L-alert was used for the first time to provide life support information during the emergency restoration period after the Kumamoto earthquake. One damaged town sent information such as administrative procedures information to L-alert, two broadcasting stations and one IT companies transmitted the residents. Based on participation observation and interview surveys on the parties concerned, we concluded that L-alert is useful for providing life support information during the emergency restoration period.
