Abstract This paper is the fourth in a series on a play fairway analysis of geothermal resources across the State of Hawai‘i. Here we describe recent exploration activities that include groundwater sampling in ten locations statewide, as well as geophysical surveys on Lāna‘i, across the SW rift of Haleakalā Volcano (Maui), and surrounding Mauna Kea Volcano (Hawai‘i Island). We derive a first-order method for computing topographic stress using Green’s functions, finding that topography can induce appreciable crustal stress. We develop a new method for incorporating depth information about resistivity, density, and topographic stresses into our previously published equations to calculate resource probability and confidence. We incorporate newly collected and modeled data into our calculations to update statewide maps of probability and confidence. Lāna‘i Island and southeast Mauna Kea are identified as the top targets for exploratory drilling. The east rift of Haleakalā Volcano, the southern-most region of Mauna Loa’s SW rift (Hawai‘i Island), and central Kauai are identified as targets for geophysical surveying.

Play Fairway 对整个夏威夷州的地热资源进行分析：4. 更新了新的地下水化学、地下应力分析和重点地球物理调查

摘要 本文是对整个夏威夷州地热资源进行球道分析的系列文章中的第四篇。在这里，我们描述了最近的勘探活动，包括在全州 10 个地点进行地下水采样，以及对拉奈岛、哈雷阿卡拉火山（毛伊岛）的西南裂谷和周围的莫纳克亚火山（夏威夷岛）进行的地球物理调查。我们推导出使用格林函数计算地形应力的一阶方法，发现地形可以引起可观的地壳应力。我们开发了一种新方法，将有关电阻率、密度和地形应力的深度信息纳入我们之前发布的方程，以计算资源概率和置信度。我们将新收集和建模的数据合并到我们的计算中，以更新全州范围的概率和置信度图。Lāna'i 岛和 Mauna Kea 东南部被确定为勘探钻探的首要目标。Haleakalā 火山的东部裂谷、Mauna Loa 西南裂谷（夏威夷岛）的最南端区域和考艾岛中部被确定为地球物理测量的目标。
