Assessing Wide-area Logistics Support Base in the Vicinity of Impacted Area Based on the Survey of the Great East Japan Earthquake

Abstract

This study developed the method to assess wide-area logistics support base in the vicinity of impacted area that remarkably functioned after the Great East Japan Earthquake. We analyzed the spatial allocation of rescue organization headquarters and concluded substantial life service, less than 50km from impacted areas, accessible to multiple impacted areas, and large space facility as the required conditions. Addition to seismicity and tsunami by the Great Earthquakes along the Nankai Trough, these conditions are applied into Kii Peninsula and Shikoku area in a suitability analysis. It clearly identified 6 sets of wide-area logistics support bases,impacted areas, and unavailable areas. The method demonstrates location of wide-area logistics support base for wide area disaster management.
