Fluids are expected to profoundly modify the seismic properties of the cracked rocks of Earth's upper crust (to depths of about 15 km) but there are so far few relevant laboratory measurements. Through the development and application of novel experimental techniques we plan to build a better laboratory-based understanding of the seismic properties of fluid-saturated crustal rocks. The outcome will be an improved capacity to monitor the presence of fluids in diverse situations ranging from geothermal power generation and waste disposal to earthquake fault zones.

流体有望深刻地改变地球上地壳（深度约15公里）破裂岩石的地震特性，但迄今为止相关的实验室测量很少。通过开发和应用新的实验技术，我们计划建立一个更好的基于实验室的理解流体饱和地壳岩石的地震性质。其结果将是提高监测从地热发电和废物处理到地震断裂带等各种情况下流体存在情况的能力。
