On the National Resilience Plan for the Recovery of 3.11 Earthquake and Tsunami Disasters

Abstract

After 3.11 Earthquake and Tsumani Disaster, for 5 years, we have been observing and image-recording the reconstructions of land-defense as the recovery processes at the disaster places. They are planned as the National Land Resilience Plan. In this plan software-resilience has been emphasized along with the hardware reconstruction of great seawalls. We discuss the role of the software resilience as the disaster reduction manner from the view of our hardware reconstruction records, and the coordination of the software-hardware cooperative defenses. Then, we emphasize the system of systems approach for the planning and realizing the disaster-free societies by suitably combining the software and hardware resiliences.
