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. ***

9406378 Meyer这项研究是分析一个独特的30 GB、70个地点的地震数据集，这是1991年和1992年在其他地方支持部署的便携式数字记录三分量长和短周期地震仪在俄罗斯中部相干阵列中的结果。这些阵列覆盖了西伯利亚克拉通、贝加尔湖隆起、贝加尔河裂谷以及延伸到蒙古的湖泊以南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。有待回答的问题是，今天的贝加尔裂谷是被动的还是主动的构造特征，也许，它最初是什么？这些结果将与其他新生代地震活跃的裂谷进行比较，例如今天正在研究的肯尼亚和里奥格兰德，使用相同的工具和方法。这项研究是国家减少地震灾害计划的一部分。***
