Stress-Tensor Orientations in Central Alaska Based on Fault Plane Solutions

这项研究将集中在阿拉斯加中南部的应力方向。应力张量将通过对大量中小地震的断层面解的分析来估计。德纳利断裂和深俯冲带的变化在该地区走向明显，其中一个需要解决的问题是，应力变化如何与断裂的走向变化和深度相关联。这些都是关系到阿拉斯加地震危险性和构造的根本问题。这项研究是国家减少地震灾害计划的一部分。

This research will concentrate on the orientation of stress in south-central Alaska. Stress tensors will be estimated by means of analysis of fault plane solutions for large numbers of small to medium magnitude earthquakes. The Denali fault and the deep subduction zone changes strike markedly in this area and one of the questions to be addressed is how the stress changes relate to the strike changes and depths of the faults. These are fundamental questions that bear on the seismic hazard and tectonics of Alaska. This research is a component of the National Earthquake Hazard Reduction Program.
