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年在夏威夷的基拉韦厄火山和莫阿纳洛亚火山的海底侧翼进行了海洋反射勘测。 本次勘测的炮点数据由夏威夷火山观测站维护的永久陆地地震阵列记录。 在勘测区域到达的射线路径采样了大量的火山碎屑和海底洋壳，在近海-陆上过渡处有碎屑覆盖。 将对这些数据进行处理和反演，以获得火山速度结构的3D层析图像。
