This document discusses how seismic activity can impact supply chain management and strategies for preparation and response. It first notes how recent earthquakes in Japan disrupted supply chains for various industries. The rest of the document outlines a four-step approach to managing seismic supply chain risks: 1) identify risk factors and levels of exposure, 2) define mitigation strategies, 3) implement strategies, and 4) monitor practices. It provides examples of strategies like avoidance, postponement and security. The document also discusses resilience and how companies, organizations and governments can respond more broadly to seismic events.
