Analysis and Measurement of 3-D Spatial Variations of Earthquake Strong Ground Motion

这一行动是为了继续支持美国和台湾合作的记录和传播强震数据的研究项目(NSF CES-8417856)。这一研究设施名为SMART-1(台湾强震台阵)，是安装在台湾地震高发区的大型数字强震台阵。这是加州大学伯克利分校与台湾大学地球科学研究所中央研究院的合作项目。SMART-1台阵于1980年9月开始运行，在运行的头6年半时间里，已经记录了50多次里氏3.8-7.0级地震的强震记录。这些强震记录为地震工程和理解近场强震提供了重要资源。这一持续合作的目标是：(1)支持对已经记录的强震数据集的研究，包括1986年11月15日7.8级地震，以及(2)协助将阵列的主要部分搬迁到具有更坚固(更坚硬)地基条件的同一高地震区的新地点。这将为在坚硬的土壤和岩石场地上建造的建筑物提供地震响应数据。

This action is for continued support of a U.S.-Taiwan cooperative research project (NSF CES-8417856) to record and disseminate earthquake strong ground-motion data. This research facility, called SMART-1 (Strong Motion ARray in Taiwan -1), is a large-scale digital strong-motion array installed in a highly seismic area of Taiwan. It is a collaborative project between the University of California at Berkeley and the Academia Sinica of the Institute of Earth Sciences at the National Taiwan University. The SMART-1 array commenced operation in September 1980, and in the first 6 1/2 years of operation, strong-motion records from over 50 local earthquakes of magnitude between 3.8 and 7.0 (Richter scale) have been recorded. These strong-motion records represent an important resource for earthquake engineering and for the understanding of seismic strong motion in the near field. The goals for this continued cooperation are: (1) To support research on the strong-motion data sets already recorded, including the magnitude 7.8 earthquake on November 15, 1986, and (2) to assist in the relocation of a major part of the array to a new site in the same highly seismic region, with firmer (stiffer) ground foundation conditions. This will provide earthquake response data for structures built on stiff soil and rock sites.
