This project is part of the NSF/USGS initiative within the National Earthquake Hazard Reduction Program (NEHRP) to investigate the effects of the Loma Prieta earthquake of 17 October 1989. It concerns the observed performance of six sanitary landfills located within the Loma Prieta earthquake damage zone. Immediately following the Loma Prieta earthquake, these landfills were inspected for damage and evidence of slope movement, and the observations recorded. The objectives of this research program are: (1) to estimate the mean peak ground acceleration that these landfills were subjected to during the earthquake; (2) use these estimated ground accelerations in a deformation analysis; (3) compare the predicted deformations with the observed conditions; and (4) based upon this comparison, to assess the validity of the input parameters and the analytical techniques used.

该项目是美国国家科学基金会/美国地质勘探局国家减少地震灾害计划(NEHRP)倡议的一部分，目的是调查1989年10月17日洛马普里塔地震的影响。它涉及位于洛马普里埃塔地震灾区内的六个卫生垃圾填埋场的观测性能。洛马普里埃塔地震发生后，立即对这些堆填区进行了检查，以确定是否有损坏和斜坡移动的证据，并对观测结果进行了记录。这项研究的目标是：(1)估计这些垃圾填埋场在地震期间受到的平均峰值地面加速度；(2)在变形分析中使用这些估计的地面加速度；(3)将预测的变形与观测情况进行比较；以及(4)在此比较的基础上，评估输入参数和使用的分析技术的有效性。
