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.

这项研究调查了夏威夷火山岛大地震的原因，这是一个及时而有争议的问题。地震方法是在永久和临时地震仪上记录来自本地和远处地震的波，以勾勒出火山桩-海洋地壳界面处埋藏沉积层的范围。如果这一层的深度与考伊基断裂带观测到的低角度断裂地震重合，那么结果将支持主要地震是沿该断裂带滑动的假设。由于这项研究直接涉及地震灾害，因此它是对国家地震减灾计划的贡献。
