Statistical Analysis of Post-Earthquake Disaster on the Activities of the Port Damaged by the Hyogo-ken Nanbu Earhquake

Abstract

This paper presents the effectiveness of conducting statistical analysis of the post-earthquake disaster. The Port of Kobe is chosen as a case study and hypothesis tests based on cargo time series data are conducted to determine the long-term effects of the earthquake. This test procedure is applied to the exported cargo data. It is shown that there exist not only systematic shocks but also deterministic decreasing trend. This proposed statistical test can be extended to measure the effects of implemented policies for removing the earthquake effects. This extended procedure is examined by conducting time series analysis of transhipped cargo.
