本文提出了一个概念框架来定义社区的地震复原力，以及复原力的量化测量，这对集中于增强这种复原力的协调研究工作是有用的。这一框架依赖于弹性的补充措施：“减少故障概率”、“减少故障后果”和“减少恢复时间”。该框架还包括对稳健性和快捷性的“目的”以及机智和冗余的“手段”的量化衡量，并将这些衡量纳入社区复原力的四个维度--技术、组织、社会和经济--所有这些都可用于量化各种物理和组织系统的复原力的衡量标准。然后，系统图确定实现这些目标所需的任务。这一框架可用于未来的研究，以确定不同分析单位和系统的复原力，并制定复原力目标和产生这些价值的详细分析程序。
This paper presents a conceptual framework to define seismic resilience of communities and quantitative measures of resilience that can be useful for a coordinated research effort focusing on enhancing this resilience. This framework relies on the complementary measures of resilience: "Reduced failure probabilities," "Reduced consequences from failures," and "Reduced time to recovery." The framework also includes quantitative measures of the "ends" of robustness and rapidity, and the "means" of resourcefulness and redundancy, and integrates those measures into the four dimensions of community resilience-technical, organizational, social, and economic-all of which can be used to quantify measures of resilience for various types of physical and organizational systems. Systems diagrams then establish the tasks required to achieve these objectives. This framework can be useful in future research to determine the resiliency of different units of analysis and systems, and to develop resiliency targets and detailed analytical procedures to generate these values.
