The Hengill volcanic system is located in the Reykjanes Peninsula (Iceland) and hosts two large geothermal power plants: Nesjavellir and Hellisheiði. This area is the next target for the Iceland Deep Drilling Project (IDDP) to search for super-critical fluids. Here, we investigate the potential for ambient seismic noise tomography to be used as a geothermal exploration tool. The results are compared with different geophysical observables, of which resistivity modeling shows an excellent correlation with our results. We also observe a prominent seismic velocity reduction to the south of Hverahlíð, where the most powerful boreholes in the region are located.

Hengill 火山系统位于雷克雅内斯半岛（冰岛），拥有两个大型地热发电厂：Nesjavellir 和 Hellisheiði。该区域是冰岛深钻项目（IDDP）寻找超临界流体的下一个目标。在这里，我们研究了将环境地震噪声层析成像用作地热勘探工具的潜力。将结果与不同的地球物理观测值进行比较，其中电阻率模型显示出与我们的结果极好的相关性。我们还观察到 Hverahlíð 以南的地震速度显着降低，该地区最强大的钻孔位于此处。
