Prior to the 1990s, natural disasters and their economic impacts were not a major field of study for regional economic analysts even though there was a sizeable literature based on structural engineering and geotechnical approaches. The latter approaches attempted to understand the behavior of earthquakes and to explore ways to prevent or minimize damage from the disaster should it occur. However, when decisions needs to be made on the retrofit of existing facilities as a prevention or the restoration of disrupted facilities after damages, economic considerations related to budgeting priorities have not been prominently featured. As a consequence, decisions about retrofit strategies tend to focus on engineering-based criteria (for example, bridge 21 on route 50 should be retrofitted because it presents the greatest probability of collapsing given an earthquake of magnitude x) rather than on economic criteria (for example, a 10% loss of capacity on bridge 10 on route 60 would create the greatest economic disruption under a similar earthquake scenario and hence would have the highest priority for retrofit). Hence, there is a clear need to provide some interface to explore the ways in which engineering-based assessments can be compared with those based on economic analysis tools. The current research described in this chapter provides such an interdisciplinary research effort.1
