首都直下地震に備える事前復興の取り組み―東京における震災復興対策と復興訓練から―

Abstract

Considering the immense scale of damage caused by the next Tokyo Earthquake, occurring beneath a mega-city that is the capital of Japan, a quick response requires pre-disaster measures and post-disaster recovery planning to mitigate economic losses and damage to central functions. Tokyo Metropolitan Government (TMG) learned from the Great Hanshin-awaji Earthquake of 1995, and has prepared such recovery measures.Because a huge amount of damage is expected on a scale approximately ten times as great as that caused by the Great Hanshin-awaji Earthquake, restoration from the next Tokyo Earthquake cannot be completed without the participation of citizens and enterprises. In particular, it is important for the recovery of damaged districts to be implemented through community power. Accordingly, TMG published the “Planning Manual for Post-Disaster Urban Restoration Planning” in 1997, and “Administrative Manual for Post-Disaster recovery Measures for Living” in 1998. At the same time, a new type of drill for urban recovery after an earthquake, rather than disaster response activities, was developed by TMG and Tokyo Metropolitan University.This paper summarizes pre-disaster measures for post-disaster recovery planning prepared. by TMG. Two drill programs are introduced : (1) community restoration drill program for citizens and (2) administrative staff training for post-disaster urban reconstruction planning. Finally, the positioning and roles of these two programs among disaster reduction measures are discussed.
