Reprocessing and Interpretation of Reflection Seismic Data from a Reactivated Rift in the Andean Foreland in Northwestern Argentina

本研究旨在研究西北部安第斯前陆地区 阿根廷通过重新加工和解释 国家石油公司（YPF）收集的反射地震数据 阿根廷。 再加工将提高产品质量， 在主要感兴趣的深度以下的反射数据， 例行的工业工作。 这些结果将与 利用便携式地震台网进行的地震研究 由孟菲斯州立大学安装了9个月。 这项研究是 目前处于挤压状态， 伸展作用形成的先存断层。 的组合 两个数据集将影响对构造的理解， 安第斯山前陆、造山运动与地震灾害 地区 这项研究是国家地震局的一个组成部分。 减少危害方案。

This research is to study the Andean foreland of northwestern Argentina by means of reprocessing and interpretation of reflection seismic data collected by the State Oil Company (YPF) of Argentina. The reprocessing will improve the quality of the reflection data at depths below those of primary interest in routine industry work. These results will be combined with earthquake studies done using a portable seismic network installed for 9 months by Memphis State University. The study is currently in a compressional regime that has reactivated preexisting faults formed in extension. The combination of the two data sets will bear on the understanding of tectonics of the Andean foreland, mountain building and earthquake hazard of the region. This research is a component of the National Earthquake Hazard Reduction Program.
