Analyzing the Emergency Call that is Caused by Heavy Rainfall andInvestigation of Relationship to the Sediment Disaster Warning

-Learned in Hofu City at the Chugoku, North Kyushu Heavy Rainfall in 2009-

Abstract

Public sectors should take advantage of intelligence for evacuation at a disaster. Yet, it is difficult due to unclear needs from residents and insufficient administrative resources. In this study, we collected the emergency calls published by Hofu city during the Chugoku, North Kyushu heavy rainfall in 2009. We found that it is hard for evacuees to predict the landslide. For this issue, we also collected the meteorological data associated with the landslide risk, and made a time-series comparison with the emergency calls. The method is suggested to improve the evacuation.
