This book is concerned with a number of central themes in a rapidly developing area, earthquake occurrence modelling. The book starts with an introductory chapter that sketches out the state-of-the-art earthquake modelling approaches based on Markov and semi-Markov models. In Chapter 2 the long-term seismogenesis is presented in association with the evolving stress field. The occurrence times of the earthquakes are considered to have been advanced, i.e. triggered by accumulated stress changes from past nearby earthquakes and tectonic loading on the major regional faults. Chapters 3 and 4...
