Recent decades have witnessed a rapid expansion of production networks and supply chains in East and Southeast Asia, made possible by underlying forces of technological advances and reductions in trade barriers and driven by pursuit of economies of scale and agglomeration, and greater efficiency and lower costs. The successful functioning of such finely constructed and balanced production networks and supply chains rests, however, on the premise of there being no major disruptions to the system, including natural disasters. Historical data indicate that the East and Southeast Asia region is, in fact, especially prone to a variety of natural hazards (earthquakes, tsunamis, floods, and typhoons).
