This project involves a comparative analysis of damage to public property caused by the Loma Prieta and Whittier earthquakes. Specific objectives of the study are: (1) to collect a detailed listing of physical damage to public facilities including public buildings, streets, bridges and water sewer systems and document repair and replacement costs for each class of damage; (2) to produce one way descriptive statistics that show the overall damage pattern and the damage pattern for each jurisdiction; (3) to compare the distribution of damage across types of facilities with that experienced in the Whittier Narrows earthquake and test the hypothesis that the proportion of damages for each class is the same; (4) to calculate damage ratios for various systems based on the actual losses and secondary data on the amount and value of property in each case study jurisdiction; and (5) to compare the actual damage experienced in both Whittier Narrows and the Loma Prieta earthquakes to the damage predicted by the ATC-13 damage estimation method and determine the variation of each to the predicted values.

该项目涉及对洛马普列塔地震和惠蒂尔地震对公共财产造成的损害进行比较分析。 研究的具体目标是： (1) 收集公共设施物理损坏的详细清单，包括公共建筑、街道、桥梁和下水道系统，并记录每种损坏的维修和更换费用； (2) 生成单向描述性统计数据，显示总体损害模式和每个辖区的损害模式； (3) 将不同类型设施的损坏分布与惠提尔海峡地震中的损坏分布进行比较，并检验每个类别的损坏比例相同的假设； (4) 根据每个案例研究辖区的实际损失和财产数量和价值的二手数据，计算各个系统的损坏率； (5) 将 Whittier Narrows 和 Loma Prieta 地震中经历的实际损害与 ATC-13 损害估计方法预测的损害进行比较，并确定每个地震与预测值的变化。
