Source Mechanisms for Earthquakes in Hawaii

这项研究是将以前对夏威夷地震和构造的研究扩展到夏威夷岛北部和夏威夷群岛的其余部分。这些地区的地震活动比迄今为止研究过的地区要少，也没有构造模型可以解释地震的存在。之前的研究分析了考伊基（位于两座火山基拉韦厄火山和莫纳罗亚火山之间）、基拉韦厄火山（1868年大地震的次震区）和夏威夷西部地震的250个断层面解决方案。由此得出的应力方向和构造模型的估计与夏威夷岛链的地震危险性问题有关。这项研究是国家减少地震危害计划的一个组成部分。

This research is to extend previous research on Hawaiian earthquakes and tectonics to the north part of the island of Hawaii and to the rest of the Hawaiian archipelago. These areas are less active seismically than those studied thus far, and no tectonic models exist explaining the presence of earthquakes. The previous study analyzed 250 fault-plane solutions for earthquakes in Kaoiki (between the two volcanoes Kilauea and Mauna Loa), in Kilea (the meizoseismal area of the great earthquake of 1868), and west Hawaii. The resulting estimation of stress directions and tectonic models bear on the question of seismic hazard in the Hawaiian island chain. This research is a component of the National Earthquake Hazard Reduction Program.
