Geophysics, or physics modelling of geological phenomena, is as old and as - tablished as geoscience itself. The statistical physics modelling of various g- physical phenomena, earthquake in particular, is comparatively recent. This bookintendstocovertheserecentdevelopmentsinmodellingvariousgeoph- ical phenomena, including the imposing classic phenomenon of earthquakes, employing various statistical physical ideas and techniques. This ?rst book on statistical physics modelling of geophysical phenomena contains extensive - viewsbyalmostalltheleadingexpertsinthe?eldandshouldbewidelyuseful to the graduate students and researchers in geoscience and statistical physics. It grew out of the lecture notes from a workshop on "Models of Earthquakes: Physics Approaches", held in Saha Institute of Nuclear Physics, Kolkata, - der the auspices of its Centre for Applied Mathematics and Computational Science in December 2005. The book is divided in four parts. In the ?rst part, tutorial materials are introduced. Chakrabarti introduces the fracture nucleation processes, their (extreme) statistics in disordered solids, in ?bre bundle models and in the two fractal overlap models of earthquakes. In the next two chapters, Hemmer et al. and Kun et al. review the avalanche or quake statistics and the bre- ing dynamics in simple (mean-?eld like) ?bre bundle models and in their extended versions, respectively. Hansen and Mathiesen discuss the scale - variance properties of the random and fractured surfaces.
