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

小行星9706374 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数据分析中心，以研究两个目标地区的活跃地壳变形，即加州的圣弗朗西斯科湾地区，沿着圣安德烈亚斯断层系统的一个复杂接合处，以及亚洲中部大喜马拉雅山脉沿着的应变积累带。 这些测量补充了GPS（全球定位系统）和水准测量数据，以更好地约束主动变形过程的模型。 分析震间断层和应变积累将有助于加深对目标地区地震危险性的认识。 本次调查的结果将包括沿圣安德烈亚斯断层系统的蠕动和锁定段沿着的复杂分布的详细绘图，弗朗西斯科湾地区相互作用的断层之间的应变分布的更好的模型，以及沿喜马拉雅沿着M8级地震破裂带的下倾边缘附近的应变积累区的更好的定义。 ***

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. ***
