As a result of the International Workshop on Strong-Motion Earthquake Instrument Arrays in Hawaii, May 2-5, 1978, and subsequent discussions, a cooperative U.S.-India project was established to organize and install an earthquake strong motion accelerograph array in India. In August 1983, installation of 49 accelerograph stations was completed in the epicentral region of the Great Kangra Earthquake of 1905 in India. Since 1983, this array has been maintained by the staff of the University of Roorkee, India. Later, another strong motion array of 50 stations was installed in the area of Shillong, Assam, where a great earthquake of magnitude 8.7 occurred in 1897. Arrays such as these provide invaluable data whenever they are able to record a large earthquake, data which is used to better understand the processes causing earthquakes, the ground shaking resulting from large earthquakes, the effect on the stability of soil structures at a particular construction site, the response of a building or structure at that site, and the damage and loss of life that could result from damage and collapse of soil structures and buildings. Since large earthquakes are rare events, it is essential that strong motion arrays be placed in any place in the world where strong earthquakes are expected within the next decade or two. This action will assist in obtaining such data from these two crucial arrays in India, one of which was installed as cooperative agreement between the U.S. and India. The purpose of this action is to continue and to extend the accomplishments of this effort and to archive, digitize, and publish already available strong motion data in India, so that a complete detailed data gathering program can be set up for future research and its applications: all scientists and engineers involved in earthquake hazard reduction can benefit from this effort by having a sound experimental basis for their analyses and engineering applications.

关于强运动的国际研讨会 1978年5月2-5日在夏威夷的地震仪器阵列， 随后的讨论，一个合作的美国-印度项目是 建立了组织和安装地震强烈运动 印度的加速器阵列 1983年8月，安装了49个加速器站， 在康格拉大地震的震中地区完成 1905年在印度 自1983年以来，这一阵列一直由 印度鲁尔基大学的教职员工。 后来，另 在该地区安装了由50个台站组成的强震阵列， 阿萨姆邦的西隆发生了8.7级大地震 发生在1897年。 这样的阵列无论何时都能提供宝贵的数据， 能够记录一个大地震，数据，这是用来更好地 了解地震的发生过程， 由于大地震的影响， 土壤结构在一个特定的建筑工地，响应 的建筑物或构筑物的损坏和损失， 土壤的破坏和塌陷可能导致的生命的 结构和建筑物。 由于大地震是罕见的 事件，这是必不可少的强震阵列被放置在 世界上任何一个预计会发生强烈地震的地方 在未来的一二十年内。 这一行动将有助于 从印度的这两个关键阵列中获得这样的数据， 其中一项协议是作为美国与美国之间的合作协议而建立的。 和印度 这一行动的目的是继续和扩大 这一努力的成果，并存档，存档， 发布印度已有的强震动数据，以便 可以为将来建立完整详细的数据收集程序 研究及其应用：所有科学家和工程师 参与减少地震灾害的人可以从中受益 通过为他们的分析提供良好的实验基础， 和工程应用。
