Seismic Investigation of the Kaokiki Fault Zone: the Origin of Large Earthquakes in Hawaii

这项研究调查了夏威夷火山岛上发生大地震的原因，这是一个及时而有争议的问题。地震方法是在永久地震仪和临时地震仪上记录来自本地和远程地震的波，以勾勒出火山桩-海洋地壳交界处埋藏的沉积层的范围。如果这一层与在Kaoiki断裂带观测到的小角度断裂地震在深度上重合，结果将支持大地震是沿该带滑动的假说。因为这项研究直接涉及地震灾害，所以它是对国家防震减灾计划的贡献。

This research investigates the cause of major earthquakes on the volcanic island of Hawaii, a timely and controversial question. The seismic method is to record on both permanent and temporary seismometers the waves from local and distant earthquakes to outline the extent of the buried sediment layer at the volcanic pile-ocean crust interface. If this layer coincides in depth with the low-angle-faulting earthquakes observed in the Kaoiki Fault Zone, the results will support the hypothesis that major earthquakes are slips along this zone. Because this research deals directly with earthquake hazard, it is a contribution to the National Earthquake Hazard Reduction Program.
