This a post-event investigation project to learn engineering lessons from the Loma Prieta earthquake (October 1989). The objective of this project is to improve the reliability of the existing earthquake loss estimation models based upon observations of the October 17 Loma Prieta earthquake. Research will be focused on two issues: * the amplification of ground motion due to certain soil conditions, and * a Bayesian update of the loss estimate matricies for various classes of buildings. The study will comprise of four tasks: (1) Data collecting and processing, (2) development of soil amplification model, (3) Bayesian update of intensity-damage relationships, and (4) calibration of the updated integrated loss estimation model developed earlier by the investigators at Stanford University. A successful completion of the project will advance the state of the art in earthquake risk management to the benefit of all segments of society.

这是一个学习工程学的事后调查项目 1989年10月洛马普列塔地震的教训。 本项目的目标是提高可靠性 现有的地震损失估算模型， 10月17日洛马普列塔地震的观测结果。 研究将侧重于两个问题： * 地基土对地震动放大作用 条件和 * 损失估计矩阵的贝叶斯更新， 各种 建筑物的等级。 这项研究将包括四项任务： (1)数据采集 （2）建立土壤放大模型， (3)强度-损伤关系的贝叶斯更新，以及（4） 更新的综合损失估计模型的校准 由斯坦福大学的研究人员早些时候开发的。 该项目的成功完成将推动国家 最先进的地震风险管理技术，造福所有人 社会的各个部分。
