对2001年2月尼斯奎利地震中城市电力分配系统的性能进行了评估。确定了地震后生命线的恢复率；估计了停电持续时间的分布；并利用地理信息系统(GIS)方法确定了生命线损坏与仪器修正的麦卡利烈度、最大地面速度和最大地面加速度之间的关系。利用Logit回归分析，得出了生命线的脆性曲线，其方式类似于O‘Rourke的水线性能公式(O’Rourke et.艾尔2000)。将该模型外推到西雅图断层地震情景中，验证了其预测的可行性。
The performance of an urban electric utility distribution system was evaluated for the February 2001 Nisqually earthquake. The restoration rate of the lifeline following the event was determined; the distribution of outage durations was estimated; and correlations between lifeline damage and instrumental Modified Mercalli intensity, peak ground velocity, and peak ground acceleration values were ascertained using a GIS (geographical information systems) approach. Using a logit regression analysis, a fragility curve was developed for the lifeline in a manner similar to O'Rourke's formulation of water-line performance (O'Rourke et. al. 2000). Extrapolation of the model to the Seattle Fault earthquake scenario was made to demonstrate its feasibility for prediction.
