Are There Any Chronological Changes in Residents’ Disaster Mitigation Consciousness and Anti-disaster Activities?

An Analysis based on Nation-wide Web Survey Conducted in 2010, 2011 and 2015

Abstract

While the catastrophic results of East-Japan Great Disaster on March 11th 2011 remind us that self-help and mutual-help to disaster are as important as public-help, residents’ prevention consciousness and anti-disaster activities against natural disasters such as earthquakes, landslides, floods and tsunamis are far from adequate. In this paper, based on three nationwide web surveys on self and mutual help consciousness and anti-disaster activities conducted in 2010, 2011 and 2015 we analyze the results and verify whether there exist regional differences and temporal change in consciousness and anti-disaster activities against natural disasters.
