東日本大震災における港湾物流へのインパクトと 海運・港湾部門のレジリエンス機能

Abstract

The 3.11 East Japan Great Earth Quake and the tsunami completely paralyzed port functions in Tohoku and north Kanto regions, and resulted in long-continued disruption of shipping links to/from Tohoku region. Lessons learnt from the quake include an unexpected delay in mobilizing rehabilitated port functions for commercial ship calls, and identified advantages of ferry boats as multi-modal transportation means before completion of restoring port facilities. This paper discusses, analyzes and summarizes an impact and rehabilitation process of Tohoku ports damaged by the quake by focusing on the resumed ship calls after the disaster. Strategic approaches for mobilizing ferry boats are also discussed for not only securing emergency relief logistics but for assisting in recovery of damaged regional supply chain.
