Developing Resiliency Measures to Reduce Seismic Hazard Impact in the Central United States

摘要

When a damaging seismic event occurs in an area, fatalities and injuries happen; damage to building structures and infrastructure systems occurs resulting in short-term and long-term economic losses and disruptions to societal systems. Given a particular damaging seismic event, the consequences of the event on a community depend on several factors: primary among them are the vulnerabilities of physical and socio-economic systems, and exposure to the damaging seismic event. The seismic risk to a community is a function of hazard, vulnerability, and consequences. The impact on the community due to a damaging seismic event is shown in Figure 10-1. The author is of the opinion that the total seismic risk comprises of technical, economic and societal components. Thus, the seismic hazard impact reduction needs a community systems-level approach that necessarily includes interaction of technical systems, economic systems, and societal systems within the constraints of existing organizational systems.
