Seismic Reflection Imaging of the Northridge Earthquake Epicentral Region

小行星9416773 该项目将从1994年1月17日北岭地震的震中地区采集、再处理和解释60-200英里的近期工业地震反射数据。 这些数据将被用来提供对北岭地震震源区地质模型的限制，并研究震中区断层的几何形状。 这些结果将与作为洛杉矶地区地震实验的一部分收集的地震折射数据相结合，通过北岭震中。 这些数据是使用可控震源来源收集的，将由雪佛龙和至少三家其他公司提供。 这项研究被美国地球物理研究所采用，作为他们的首批试点项目之一，以存档和公开不再具有商业利益但具有社会和/或科学意义的数据。 研究结果将提供北岭地震的成因断层、可能的中地壳拆离面和莫霍面的图像，从而为该地区的所有力学和运动学模型提供重要的制约因素。

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.
