The risk associated with earthquake hazards on highway systems is dependent on the complexity of a network and its redundancy in providing traffic flow. Earthquake loss estimation studies can provide decision makers with an appreciation of the importance of having a highway network resistant to earthquakes and information to make the network resistant to these events. The direct economic loss was estimated for a major metropolitan area, St. Louis, for a series of earthquake scenarios. The primary component of the study was damage to bridges within the highway system. The study zone covers the St. Louis metropolitan area and its …

The long recurrence period and high consequence earthquakes events in the New Madrid Seismic Zone have caused some federal agencies (e.g., NEHRP, FHWA) to look at the more densely populated areas where higher seismic risk is present. This paper presents the data collection, interpretation, and analysis of the geotechnical information required for an earthquake loss estimation study in St. Louis metro area. The loss estimation study was limited to the highway transportation system, where only the major highways were considered. The project information was processed using a GIS, and the subsequent loss analysis was executed using the HAZUS-MH program.
