Abstract

Following a damaging earthquake, "business interruption" (BI) -- reduced production of goods and services -- begins and continues long after the ground shaking stops. Economic resilience reduces BI losses by making the best use of the resources available at a given point in time (static resilience) or by speeding recovery through repair and reconstruction (dynamic resilience); in contrast to mitigation that prevents damage in the first place. Economic resilience is an important concept to incorporate into economic loss modeling and recovery and contingency planning. Dimensions of a refined economic resilience framework include applicability of resilience strategies to inputs and output, demand and supply side effects, inherent and adaptive abilities, and levels of economies. It provides a means to organize and share strategies that enhance economic resilience; identify overlooked resilience strategies; and present evidence and structure of resilience strategies for economic loss modelers. Numerous resilience strategies are compiled from stakeholder discussions about the ShakeOut Scenario (Jones et al., 2008). Modeled results of ShakeOut BI losses reveal variable effectiveness of resilience strategies across sectors given lengthy disruptions caused by fire-damaged buildings and water service outages. Resilience is a complement to mitigation and may, in fact, have cost and all-hazards advantages.
