摘要

So farPoroelasticity, in this book, we have assumed linear elastic solids as the medium for considering deformationDeformation and ruptures. However, as is well known, rocks near the Earth's surface have many small-scale poresPore when examined closely, and they often contain fluids, especially those in and near fault zonesFault zone. We have abundant but indirect evidence suggesting that faults and surrounding damage zones act as fluid conduits in the shallow crust. Examples of earthquakes triggered by underground injection of high-pressure fluids and outflow of fluids in the source region during earthquakes suggest that fluid flowing through connected poresPore has a non-negligible influence on earthquake occurrence.
