Seismic Reflection Imaging of the Northridge Earthquake Epicentral Region

该项目将从1994年1月17日北岭地震的震中地区获取、再处理和解释60-200英里的近期工业地震反射数据。这些数据将用于为北岭震源带的地质模型提供约束，并研究震中地区断层的几何形状。这些结果将与洛杉矶地区地震实验收集的地震折射数据相结合，这些数据贯穿了北岭震中。这些数据是用可控震源收集的，将由雪佛龙和至少其他三家公司提供。这项研究被美国地球物理研究所采纳，作为他们第一个将不再具有商业利益但具有社会和/或科学相关性的数据存档和公开的试点项目之一。研究结果将为北岭地震、可能的地壳中剥离面和莫霍断层提供因果断层的图像，从而为该地区的所有力学和运动学模型提供重要的约束。

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.
