Laboratory Controlled Experiments of Rock Fracture and Induced Seismicity

裂缝在自然界的各个尺度上都很重要，从矿物颗粒微裂缝到构造板块边界。它们产生地震，控制流体流动，在工程规模上降低地下结构周围岩石的完整性。地球上的传感器记录下的地震使地震学家能够绘制出地球内部结构的详细图像。同样，在实验室可控条件下收听小尺度的诱导压裂，并使用相同的地震学技术与高频传感器来成像裂缝的生长，并监测它们对岩石变形和流体流动的影响。

Fractures are important at all scales in nature from mineral grain micro-cracks to tectonic plate boundaries. They create earthquakes, control fluid flow and at the engineering scale reduce the integrity of rock around underground structures. The recording of earthquakes on sensors all around the earth has allowed seismologists to create detailed images of the internal structure of the earth. In a similar way, it is possible to listen to small scale induced fracturing in the laboratory under controlled conditions and use the same seismology techniques with high frequency sensors to image the growth of fractures and monitor their effect on rock deformation and fluid flow.
