Active Tectonics of Diffuse Intracontinental Deformation

9418784韦尼克这是一个项目，涉及在整个盆地和山脉安装和监测一个连续的全球定位系统网络。科学目标是确定大地测量确定的应变是集中在历史上最高的地震矩释放带内，与弹性回弹理论一致，还是以更分散的方式扩散。到目前为止，陆基和天基大地测量技术在解决板内应变积累的不均质性方面都取得了有限的成功，因为板内断裂带的滑动速率通常处于或低于常规GPS或陆基测量的分辨率水平，即约1毫米/年。然而，随着GPS连续监测技术的发展，1毫米/年的速度在不到5年的时间内就可以解决。有了适当的网络设计，整个漫射造山带的高分辨率运动学图像现在是触手可及的。***

9418784 Wernicke This is a project involving the installation and monitoring of a continuous GPS network across the Basin and Range. The scientific goal is to determine whether the geodetically determined strain is concentrated within bands of historically high seismic moment release, consistent with the elastic rebound theory, or is spread out in a more diffuse manner. Until now, both land- and space- based geodetic techniques have had limited success in resolving heterogeneity in intraplate strain accumulation, because the slip rates along intraplate fault zones are usually at or below the level of resolution for conventional GPS or land-based surveys, or about 1mm/yr. However, with the technique of continuous GPS monitoring, rates of 1mm/yr are resolvable in less than five years. With appropriate network design, a high-resolution kinematic image of an entire diffuse orogen is now within reach. ***
