In the project combined Global Positioning System satellite and undersea acoustic techniques will be used to study seafloor crustal deformation on the southeast flank of Kilauea volcano, Hawaii.. The subaerial portion of Kilauea is being monitored by an extensive network and continuous displacement rates of more than 10 cm/year have been measured on the southeast flank fault system. The submerged portion of the southeast flank is an excellent site for application of seafloor geodetic techniques since it is a region of significant crustal deformation. During the first year eight acoustic transponders will be deployed on bench marks, and the benchmarks re-occupied during the second and third year.

在该项目中，全球定位系统卫星和海底声学技术将用于研究夏威夷基拉韦厄火山东南侧的海底地壳变形。基拉韦厄的陆上部分正由一个广泛的网络监测，在东南侧翼断层系统上测得的连续位移率超过10厘米/年。 东南侧的水下部分是应用海底大地测量技术的最佳地点，因为它是一个地壳变形严重的区域。 在第一年，将在基准点上部署八个声波转发器，在第二年和第三年重新使用基准点。
