报告摘要：

Hydraulic fracturing is a method routinely used in oil and gas extraction and in the development of engineered geothermal systems. This method increases the permeability of source rock, making it possible for oil, gas, or heat, to be recovered. While applied frequently, there are many aspects of hydraulic fracturing that are not well understood, such as the induced seismicity produced during these operations. While this induced seismicity is useful to monitor the hydraulic fracturing processes, it may also cause fear to nearby communities. We will discuss several cases where induced seismicity has been observed that illustrate several aspects of the seismicity. We will discuss the mechanisms of hydraulic fracturing and how earthquakes are caused by it. Finally we will discuss the benefits of studying the induced seismicity.

Michael Fehler received his Ph.D. in seismology from MIT in 1979. He is currently a Senior Research Scientist in the Department of Earth, Atmospheric, and Planetary Sciences at Massachusetts Institute of Technology. He was Project Manager for two projects of the SEG Advanced Modeling consortium that are focused on geophysical modeling. He was Editor-in-Chief of the Bulletin of the Seismological Society of America for nine years beginning in 1995 and president of the Seismological Society of America from 2005-2007. He has coauthored a book on seismic wave propagation and scattering that was published in 1998 and a second edition of the book in 2012. His interests include seismic imaging, reservoir characterization, seismic scattering, geothermal energy, and induced seismicity.
