This action is to support a preliminary assessment and planning for the seismic instrumentation of the Loma Los Colorados waste disposal facility in the outskirts of Santiago, Chile. The Loma Los Colorados solid waste facility is now under construction. The region is exposed to frequent earthquakes, and some great earthquakes have shaken the region in historic and modern times. For example, in October 1997, the region was shaken by a magnitude 7 earthquake. At the present no comprehensive strong motion acceleration data form landfills exist. Yet, observations are crucial in order to validate results from existing numerical models. Until adequate data sets are obtained, predictions form these models of existing and proposed landfills will remain questionable. Therefore, the central and southern region of Chile is an ideal location in which to instrument engineered structures in anticipation of strong accelerations from earthquakes.KDM, Inc. The behavior of solid waste landfills during earthquakes is a subject of concern to the designers and builders as well as to those who live near them. The builder of the Loma Los Coloados waste fill, has agreed to handle the installation, monitoring, and support of the instrumentation, and to report any records promptly to the international scientific community. This is an ideal opportunity to obtain strong motion data form an instrumented landfill shaken by a major earthquake.

该行动旨在支持对智利圣地亚哥郊区 Loma Los Colorados 废物处理设施的地震仪器进行初步评估和规划。 洛马洛斯科罗拉多州固体废物处理设施目前正在建设中。 该地区地震频发，历史上和近代曾发生过一些大地震。 例如，1997年10月，该地区发生了7级地震。 目前尚无来自垃圾填埋场的综合强运动加速度数据。 然而，为了验证现有数值模型的结果，观察至关重要。 在获得足够的数据集之前，现有和拟建垃圾填埋场的这些模型的预测仍然值得怀疑。 因此，智利中部和南部地区是安装工程结构仪器以应对地震强烈加速度的理想地点。KDM, Inc. 固体废物填埋场在地震期间的表现是设计师、建筑商以及附近居民所关心的问题。 Loma Los Coloados 垃圾填埋场的建造者已同意负责仪器的安装、监控和支持，并及时向国际科学界报告任何记录。 这是从因大地震而摇动的仪器化垃圾填埋场获取强运动数据的理想机会。
