Rock stress is fundamental to all studies involving the theory and practice of rock mechanics - whether one is interested in the formation of geological structures (folds, faults, for example), the stability of man-made structures (tunnels, caverns, mines, surface excavations) or the stability of boreholes. This comprehensive book examines the nature and origin of rock stress, and the ways in which this stress is measured. The book focuses on in situ stresses in the Earth's crust, the methods for measuring and monitoring those stresses, and their importance in rock engineering, geology and geophysics. The role of geology when estimating and analyzing stress measurements is emphasised throughout. This should be useful reading for all practising and research geologists, geophysicists, and civil, mining and petroleum engineers involved in rock mechanics and rock engineering. The book can also be used as an advanced text in rock mechanics courses. This book should be of interest to postgraduate students and practitioners in rock mechanics, civil engineering, mining and petroleum engineering.

Stress in rock is usually described the origin of in situ stresses and how gravity, within the context of continuum mechanics.
