Measuring Active Deformation Using Interferometric SyntheticAperture Radar: Applications in Central California and the Himalaya

9706374伯格曼该项目将在加州大学戴维斯分校建立一个干涉合成孔径雷达(InSAR)数据分析中心，以研究两个目标区的活跃地壳形变：加利福尼亚州旧金山湾地区，沿着圣安德烈亚斯断裂系统的复杂交界处，以及中亚大喜马拉雅山脉沿线的应变累积区。这些测量补充了GPS(全球定位系统)和水准数据，以更好地约束活动变形过程的模型。对震间断层和应变累积的分析将有助于更好地了解目标地区的地震危险性。这项调查的结果将包括沿圣安德烈亚斯断裂系统的复杂蠕动和锁定段的详细分布图，旧金山湾地区相互作用的断层之间更好的应变分布模型，以及沿喜马拉雅的8级地震破裂带下倾边缘附近的应变累积区的更好的定义。***

9706374 Burgmann This project will establish an InSAR (Interferometric Synthetic Aperture Radar) data analysis center at UC Davis to study active crustal deformation in two target areas, the San Francisco Bay region, California, along a complex juncture of the San Andreas fault system, and the strain accumulation zone along the Greater Himalaya in central Asia. The measurements complement GPS (Global Positioning System) and leveling data to better constrain models of the active deformation processes. The analysis of interseismic faulting and strain accumulation will lead to improved understanding of the earthquake hazards in the target areas. Results from this investigation will include detailed mapping of the complex distribution of creeping and locked segments along the San Andreas fault system, a better model of the distribution of strain among the interacting faults of the San Francisco Bay region, and a better definition of the strain accumulation zone near the down-dip edge of M8 earthquake rupture zones along the Himalaya. ***
