The book covers rock stress in a way such that geoscience students will be able to grasp the Cauchy Stress Principle without fear of matrix transformations in an exercise. Students interested in maths, physics and engineering will learn to cement a strain gauge on a rock specimen, measure residual strains by multiple overcoring and evaluate the results. Leading edge technology in determining stress (Kaiser Effect) is presented together with classical methods (Hydraulic Fracturing). In addition, borehole techniques (Breakouts) and drillcore techniques (Anelastic Strain Recovery) are illustrated.
With respect to stress data, locations of global interest are chosen where integrated stress determination strategies have been applied. Each case study presented has special application, like the scientific ultra-deep drilling project (KTB, Germany), drilling of seismic active fault zones (SAFOD, USA) and excavation for nuclear waste disposal (Forsmark, Sweden). Stress compilations viewed by the World Stress Map project are presented and interpreted in terms of plate tectonics.

Endorsements: "The book thoroughly and convincingly integrates in situ stress, its sources, measurement, and applications, into the fields of geophysics, geology, geomechanics, and geoengineering. It is therefore that I enthusiastically recommend Stress Field of the Earth's Crust." (Bezalel Haimson, University of Wisconsin, Madison, USA, June 2009) "I think it is a very good text that covers the most important aspects of the Kaiser effect, its mechanisms and how it can be used for stress measurements in rocks." (Alexandre Lavrov, SINTEF Petroleum Research, Norway) "It is beautifully laid out, easy to read, and impossible not to understand!. I especially like the way that many of the diagrams have such iconic simplicity so that the extranneous detail has been removed - leaving only the message that the diagram is transmitting." (John A. Hudson, Emeritus Professor, Imperial College, UK, President, International Society for Rock Mechanics) From the reviews: "The presentation of the book is clear, with an abundant bibliography. ! I found the Note boxes that summarize important results to be particularly welcome. ! In conclusion, this book is undoubtedly focused on stress field of the Earth crust. ! I definitely would recommend this book to Earth Scientists in need to better understanding of stress measurement techniques, and to Rock Mechanics engineers who want to improve their understanding of the stress field at the scale of plate tectonics."
