A marine reflection survey was conducted over the submarine flanks of Kilauea and Moana Loa volcanoes, Hawaii, in 1998. Shot data from this survey were recorded by the permanent on-land seismic array maintained by the Hawaii Volcanoes Observatory. Raypaths for arrivals over the survey region sample a large volume of the volcanic edifice and subjacent ocean crust, with densest coverage at the offshore-onshore transition. These data will be processed and inverted to obtain a 3D tomographic image of the velocity structure of the volcano.

1998年，在夏威夷基拉韦厄火山和莫阿纳罗亚火山的海底侧面进行了一次海洋反射调查。这次调查的拍摄数据由夏威夷火山观测站维护的永久陆地地震阵列记录下来。调查区域的到达者的射线路径采样了大量的火山建筑物和下伏的洋壳，其中近海-陆上交接处的覆盖最密集。这些数据将被处理和反演，以获得火山速度结构的3D断层图像。
