Fault Plane Solutions for Western Hawaii and the Kaoiki Area

这项研究的第一个目标是确定夏威夷西部震级大于3.0的地震的断层面解决方案。该地区在1951年经历了6.9级地震，但在震源构造模型或震源机制方面所做的工作很少。这项工作将是对假设的检验，即夏威夷西部的上地壳在一个薄弱的海洋沉积层上被向西推，夏威夷西部有一个共同的应力张量方向。最近的地震也应该允许研究应力张量的时间变异性。从其他工作中，这些研究人员预测，在以1994年为中心的3年时间窗口内，该地区将发生另一次6+0.5级地震。这项研究是国家减少地震危害计划的一个组成部分。

The first goal of this research is to determine fault plane solutions for earthquakes with magnitude greater than 3.0 in western Hawaii. This region experienced a magnitude 6.9 earthquake in 1951 but little work has been done on a seismo- tectonic model or focal mechanisms for the hypocentral area. The work will be a test of the hypotheses that the upper crust in Western Hawaii is being pushed westward over a weak oceanic sediment layer and that western Hawaii has a common stress tensor orientation. Recent earthquakes should also allow investigation of the time variability of the stress tensor. From other work, these researchers have anticipated another magnitude 6+0.5 earthquake in this area within a 3-year time window centered on 1994. This research is a component of the National Earthquake Hazard Reduction Program.
