Theory of Earthquake Premonitory and Fracture Processes

Oversized hardcover, xx + 648 pages, NOT ex-library. Weight over 1.2kg. Little minor wear. Book is clean and bright with unmarked text, free of inscriptions and stamps, firmly bound. Issued without a dust jacket. -- This edited volume provides a mathematical framework for the study of the preparation and initiation of seismic events. It addresses the transition of the Earth's crust from quasi-static stress accumulation to sudden, dynamic failure. By synthesising the principles of continuum mechanics, thermodynamics, and the theory of defects, the work offers a granular understanding of the 'preparation zone' where micro-cracking and dilatancy occur prior to rupture. It specifically develops the "dilatancy-diffusion" model to explain the physical coupling between rock deformation and fluid flow. The content explores the evolution of fracture as a complex, non-linear process. Technical chapters detail the mechanics of crack propagation and the role of fluid infiltration in altering the effective stress within the rock matrix. A significant portion of the work is dedicated to the identification and modelling of precursory phenomena, including dilatancy-diffusion models, seismic gaps, changes in seismic velocity ratios, and variations in b-value statistics. The analysis also investigates electromagnetic and geochemical signals, providing a theoretical basis for how these anomalies are generated by physical changes in the crust during the premonitory stage. The book remains a vital reference for physics-based earthquake forecasting and seismic hazard assessment. It bridges the gap between laboratory rock mechanics and large-scale crustal dynamics, offering the technical language required to model earthquake nucleation. As a product of the Institute of Geophysics of the Polish Academy of Sciences, the volume represents a definitive synthesis of the "Warsaw School" of theoretical seismology, presenting the research conducted over several decades. For researchers in seismology and structural geology, this volume provides the foundational data needed to interpret data streams from modern seismic networks and satellite monitoring systems.…
