The Region of the Baikal Rift, a Cooperative Program of Analysis

这项研究是为了分析1991年和1992年部署的一个独特的30 gb、70个站点的地震数据集，该数据集是在其他地方得到支持的，在俄罗斯中部采用相干阵列的便携式数字记录三分量长周期和短周期地震仪。这些阵列覆盖了西伯利亚克拉通、贝加尔湖隆起、贝加尔湖裂谷以及湖泊以南延伸到蒙古的山脉和草原的代表性部分。这将是伊尔库茨克地壳研究所和威斯康星大学麦迪逊分校之间的协调联合分析。要回答的问题是，今天的贝加尔湖裂谷是被动的还是主动的构造特征，也许，它最初是什么？研究结果将与其他新生代地震活跃的裂谷进行比较，例如肯尼亚裂谷和里约热内卢Grande裂谷，这些裂谷目前正在使用相同的工具和方法进行研究。这项研究是国家减少地震危害计划的一个组成部分。＊＊＊

9406378 Meyer This research is to analyze a unique 30-Gbyte, 70-site seismic data set as a result of 1991 and 1992 deployments, supported elsewhere, of portable digital-recording three-component long- and short-period seismographs in coherent arrays in central Russia. These arrays covered representative parts of the Siberian craton, the Baikal uplift, the Baikal Rift, and the mountains and steppes south of the lake extending into Mongolia. This will be a coordinated joint analysis between the Institute of the Earth's Crust, Irkutsk, and the University of Wisconsin-Madison. Questions to be answered are is the Baikal Rift today a passive or an active tectonic feature, and perhaps, what was it at its inception? The results will be compared with other Cenozoic seismically-active rifts, for example Kenya and Rio Grande, being studied today, using the same tools and methods. This research is a component of the National Earthquake Hazard Reduction Program. ***
