Active Tectonics of Diffuse Intracontinental Deformation

小行星9418784 这是一个涉及在整个盆地和山脉安装和监测连续全球定位系统网络的项目。 科学目标是确定大地测量确定的应变是否集中在历史上高地震矩释放的带内，与弹性回弹理论一致，或者以更分散的方式分散。 到目前为止，基于陆地和空间的大地测量技术在解决板内应变积累的不均匀性方面取得的成功有限，因为沿沿着板内断层带的滑动速率通常等于或低于常规GPS或陆基测量的分辨率水平，即约1 mm/年。 然而，利用GPS连续监测技术，可以在不到五年的时间内解决1毫米/年的速率。 通过适当的网络设计，现在可以获得整个扩散造山带的高分辨率动态图像。 ***

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. ***
