Crustal and Mantle Structure Beneath the Central California Margin: A Teleseismic Study

本研究是为了研究地壳和上地幔 加州中部使用一个新的和独立的卫星数据 太平洋天然气和电力公司在该地区收集的一套。 首先，接收器函数技术将用于研究 下洋壳的方位和可能的叠瓦作用 大陆边除了寻找 地壳厚度沿着边缘。 第二，数据集将 与美国地质勘探局的数据合并， 对陆缘下地壳和地幔的残留研究。 了解构造历史对于更好地 了解和描述潜在的地震 今天的危险。 这项研究是一个组成部分， 国家地震减灾计划。

This research is to study the crust and upper mantle beneath central California using a new and independent teleseismic data set collected in the region by Pacific Gas and Electric Co. First, the receiver function technique will be used to study the orientation and possible imbrication of the oceanic crust beneath the continental margin in addition to looking for variations in crustal thickness along the margin. Second, the data set will be merged with that of the USGS to do a 3-D seismic travel time residual study of the crust and mantle beneath the margin. Understanding the tectonic history is essential for better understanding and characterization of the potential seismic hazards present today. This research is a component of the National Earthquake Hazard Reduction Program.
