Processes of Active Deformation and Slip Transfer Along the Sierra Nevada-Great Basin Boundary Zone in the Lake Tahoe Basin

9903200施韦克特太平洋板块和北美板块的边界沿着美国西海岸的加州部分是分散的。 最近的测量表明，Sierra内华达州地块相对于稳定的北美正以每年约10毫米的速度向北移动，这约占太平洋/北美相对运动总量的25%。 该项目的重点是在太浩湖盆地和相关的地震危险，它意味着这种活跃的应变积累的组成部分。 各种测绘、结构和地震研究的目的是解决目前关于活动变形原因的两种假设。 收集的数据也将适用于评估该地区的地震危险性。

9903200SchweickertThe boundary between the pacific plate and the North American plate is diffuse along the California sector of the West Coast of the US. Recent measurements indicate that the Sierra Nevada block is moving northward relative to stable North America at about 10mm/yr, which is about 25% of the total Pacific/North America relative movement. This project focuses in detail on the component of this active strain accumulation in the Lake Tahoe basin and the associated seismic hazard it implies. A variety of mapping, structural and seismic studies are aimed at resolving two current hypotheses for the cause of active deformation. Data collected will also be applicable to assessing the seismic hazard potential of this area.
