A proof-of-concept study was conducted in 1998 to improve seismic constraints on the cause of Hawaiian swell relief. Eight ocean-bottom pressure gauges were deployed in a hexagonal array to the southeast of the Hawaiian Islands. The data collected in this study was used to construct a one-dimensional model of the structure beneath the array. This continuation will extend the analysis to a three-dimensional image of the isotropic structure beneath the array and assess the anisotropic structure. Data from land-based stations will be used to augment the existing data.

1998年进行了一项概念验证研究，以改善夏威夷涌浪缓解原因的地震限制。 八个海底压力计以六边形阵列部署在夏威夷群岛东南部。 本研究中收集的数据用于构建阵列下方结构的一维模型。 这种延续将分析扩展到阵列下方各向同性结构的三维图像，并评估各向异性结构。 将利用陆基台站的数据来补充现有数据。
