This grant provides support to analyze data gathered from other funding in a region of the San Andreas fault at San Francisco bay. The data was recorded from a USGS active marine seismic profile across the ocean-land transition and up the East Bay. The goal is to use fan-geometry deployments to provide structural information constraining the depth of penetration of the individual strike-slip faults in the area. In-line geometry recordings will be used to measure velocities across the faults to constrain the maximum depth to which velocity differences occur across the individual strike-slip faults. This research is a component of the National Earthquake Hazard Reduction Program.

这笔赠款为分析从旧金山湾圣安德烈亚斯断层地区其他基金收集的数据提供了支持。这些数据是从美国地质勘探局活跃的海洋地震剖面记录的，横跨海洋-陆地过渡和东湾。其目标是使用扇形几何展开来提供限制该地区个别走滑断层的穿透深度的构造信息。同轴几何记录将被用来测量跨断层的速度，以限制跨单个走滑断层出现速度差异的最大深度。这项研究是国家减少地震灾害计划的一部分。
