9416773 Okaya This project will acquire, reprocess and interpret 60-200 miles of recent industry seismic reflection data from the epicentral region of the January 17, 1994 Northridge earthquake. The data will be used to provide constraints on geologic models of the Northridge earthquake source zone and to study the geometry of faulting in the epicentral region. The results will be integrated with seismic refraction data collected as part of the Los Angeles Region Seismic Experiment through out the Northridge epicenter. The data, which was collected using Vibroseis sources, will be provided by Chevron and at least three other companies. This study is being adopted by the American Geophysical Institute as one of their first pilot projects to archive and make public data that are no longer of commercial interest but that have societal and/or scientific relevance. The results will provide images of the causal fault for the Northridge earthquake, possible mid-crustal detachment surfaces and the Moho, and will thus provide important constraints for all mechanical and kinematic models of the region.

9416773 OKA这个项目将从1994年1月17日的诺斯里奇地震中的地震地区获取，重新处理和解释60-200英里的近期行业地震反射数据。 数据将用于对北山地震源区域的地质模型提供约束，并研究地震区域断层的几何形状。 结果将与通过北方北方震中的洛杉矶地区地震实验的一部分收集的地震折射数据集成。 使用Vibroseis来源收集的数据将由雪佛龙和至少三家公司提供。 这项研究被美国地球物理研究所（American Geophysical Institute）作为其最早的归档试点项目之一，并制作出具有社会和/或科学意义的公共数据不再具有商业利益。 结果将为北山地震，可能的中壳脱离表面和Moho提供因果断层的图像，因此将为该地区的所有机械和运动模型提供重要的约束。
