Abstract
Scientific modeling systems contain extraordinary amounts of data and produce mountains of output. These systems, often utilize Geographic Information Systems (GIS), offer almost limitless options for providing the user with informed knowledge. This article explores a new approach for emergency managers to harness the capability of scientific modeling systems when responding to disasters. In disaster response, emergency managers need sound situational awareness to support critical decision-making. Obtaining situation awareness is difficult because of the gap that exists between the information that emergency managers have and the information that emergency mangers need. However, comprehensive situational awareness is necessary to form accurate estimates of physical impacts and response requirements. GIS applications can be used to narrow the gap between known information and required information. This study developed a methodology for obtaining a common operating picture based on Hazus (Hazards U.S.), a GIS-based application that performs loss and risk assessments on multiple types of hazards. Hazus combines both scientific and engineering knowledge to model a disaster event. The keyf to this new method is using subject matter experts to penetrate the complex and chaotic decision environment and establish a hierarchy of relevant information based on relative importance. This study focused on the response required to save lives and property in catastrophic earthquakes.
